@Majcek Sorry about that!
You should still have the original recording files somewhere on your HD. If you can make a copy of those separately, we can then try a software patch on the GoToMeeting installation, followed by a re-conversion attempt.
In this case, I can email you the new patch if you can confirm an address that will be able to receive the file attachment: Click my Community Name in order to private confirm the email spelling.
