HELP - Update failed

I have updated my Cam2PC (shareware) to 4.6 today.
After update, Cam2PC opens for a few seconds and then closes down without any message. It is just gone :(. I also tried to use cam2pc other way, just opening a jpg file from Windows Explorer. The file opens in cam2pc full-screen mode as before, but disappears after 1...2 sec without any message.
I reinstalled the new 4.6 version twice, but no changes. The Cam2PC is gone.
After that, I installed the older version I had before, 4.5.2, again. It is working now, but I cannot use my albums any more. The old text file "cam2pc.albums" is still existing, but it cannot be used by cam2pc any more.
Unfortunately, I need one of the the album files VERY quickly!
So I need quick recommendations, how to make my cam2pc.albums file available for cam2pc again. In which solder it has to be for cam2pc to be used, etc.
Also, what is wrong with ver 4.6 installation???
Regards,
mri
