CALTECH1  I bought a license of PDF Recover and the same day it worked as advertised. I needed to unlock some documents I forgot the general password.

Unfortunately, 2 weeks after when I need to use it again, I am now in demo mode. Impossible to register it again : maximum number of activated licenses reached, no further activations possible, please order more licenses in our webshop !!!!!!

What ??? You have to spend $26 every 2 weeks ???????

No answer to emails so far and the voicemail is in german language...

So far, very frustrating experience.... (bad?)

I now see that others had the exact same problem of registration, may be I should have read them before and not buy this application...

In the meantime I actually replaced my hard drive, but any well written application (all the others I work with so far) should be able to handle hardware changes !!
