I tried the fixed version and now the decryption process starts but then, towards the end, it stops again with the following error:

Feel free to ask for more info or samples!

Regarding a linux release: purebasic is also available for linux, but I think it's not as easy as just recompiling it in linux .. maybe I will find some time to check it out.

I won't hold my breath then...
