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.

PNON  yes, I tried to contact the developer many time for reinstall the software. At first contact, there was no reply mail sending to my box. After long wait, I made others contact. No one answer. I decide buying AstoundSound with -$15 discount. I don't care that I have to pay more but good after sell service. It should has buy iWOW back policy if SRS has such no support at all.

ATLAS100  Exact same problem here, with the exact same result, no response. SRS seems to be totally non-customer responsive.

DENHETEN  For me the exact same problem to, with the exact same result, no response. SRS seems to be totally non-customer responsive. After I installed the software once on my old mac, version 3.1, I'm now not able to reinstall it on my new Mac. I sent an email twice now within the last two months and NO response at all. Don't buy this software although it seems cheap...

GRUMPFFF  Hi all,

Well after the troubles I had in the activation process and the web based support form, and to let know SRSLabs my state of mind about It, I reply an ad mail, and it seems that thinks have change, in less than a day I had 3 answers, asking what where the troubleshootings and hat were the activation codes.

I the last from Michael Gonzales, giving a brand new fully working activation code.

As I said things have changed, and it's good to tell. Now I know who to call :)

It took less than 24 hours to have the plug-in working fine, that's great.

Thank you to Michael and the SRSLabs support staff.

Regards

Raymond.
