DRAECHEN  How about following up with customer requests for support instead of posting ads in your competitors products? Might help better with sales rather than burning the bridges already built...  
(Version 2.1)

DRAECHEN  As noted in the next thread... If you already installed it once, you wont be able to use it again! Too bad! WAS great software but wont be buying it again to use the software I already paid for.  
(Version 3.1)

DRAECHEN  I think youll find that even with the original download of 1, you'll run into the problem described. The serial number is no longer valid once it was used once. Until the developer fixes this, even if you find the dmg, you still wont be able to use the software again short of buying it again. Go figure.

DRAECHEN  I would add I too had a motherboard and HD that died in my machine. Luckily I was able to restore from a Time Machine backup and the plugin no longer worked. Its ok I thought, I still have the serial number and the installer (I backed it up just in case). It didnt work after the restore, the reinstall etc. Said the serial number was already used.

Just like yourself I understand the anti piracy side of things. I emailed them. No response. I found the contact us link on their support page. No response. Three attempts, I gave up.

I will NEVER buy this software again (version I owned worked fine but with a single use of the installer better pray you never need to reinstall anything) I recommend against buying this software, no matter how it works.

DRAECHEN  It looks like Frodo is right.... From their own website:

"Note: IDrive DOES NOT store the user defined encryption key anywhere on the server side. We therefore advise you to take a print of this private encryption key or archive this user defined encryption key in a safe location from where you can retrieve it. You cannot decrypt data backed up to IDrive without this private encryption key. Private encryption key option is available only for the Windows platform, and not for the Mac platform."

This is from their security page:

I was going to try this but this is the main concern I have with offsite backups that someone might have access to my information without my consent. I guess Ill be waiting this one out. :(

DRAECHEN  You can fine tune your controlling of the interval even more than this app may allow. (I admittedly have never used it)-There are instructions on macosxhints about setting the time inteveral:

And for your favorite plist editor to use Id suggest Text Wrangler...

DRAECHEN  @lightman972

Sadly, you missed out. You can always buy it again?  
(Version )

DRAECHEN  I too ran into a problem with finding the software. It looks like from their homepage they sold it off to Prosoft Engineering and it is being rebranded as Jax. I just wanted to reinstall it as my hd crashed and it doesnt look like this will be possible for me either until Jax is up and running. BTW- www.prosofteng.com for the new url.

DRAECHEN  Ok so you can pay money for a filemaker database that someone obviously spent a lot of time working on making sure it has a field for EVERYTHING or you can use some software that will help you manage your collection like Delicious Library. There is a reason that time and time again Delicious Library gets voted the best management software for books, dvds and software. Plus tracks who you might have lent things to and has other developers working on plugins. If you want to use the right software for the tool go here:

(Version 1.31)

DRAECHEN  Fantastic software! I just wanted to add how good I thought this software was. I download my tivo files, watch them via front row as it saves it right to my movies folder. Makes it truly a joy to use frontrow with my tivo content. Keep up the great work!
