UPDATE: The bug is fixed, the new version will be released in a few hours.
Some users have noticed a bug which appears on some systems. The bug causes the recordings to be 0kb. I think I found the problem code. But I can't test this out, because never get this bug on any available for testing systems.
If you have this problem on your system and willing to help, please contact me by mail - mail(attt)voipcallrecording.com (change attt by @). I'll send you a beta version with probably fixed bug and logger of program internal calls.
Many thanks
