I have used converter a lot, without any major problems. Now, after some Windows Vista security updates I started getting this kind of error message when starting converter:

"mediahandler.exe

The mediahandler process could not start properly.

Please check to make sure you have your firewall configured to allow it to connect."

Then, when trying to add a file to be converted I get the same message and the file is not added to list -> cannot be converted.

I tried to play with firewall without success.

Vista update screwed up something somewhere. Do you have any suggestions that what to do? This same problem has been mentioned for example in www.internettablettalk.com/forums.
