Hello,
I have exactly the same problem as "paznbazn" had few months ago.
Tried to get help from support form, but no response so trying here again.
I bought unlimited subscription few days ago, but have troubles with all apps I've tried (media player, video converter, video editor).
I can launch all of them but when any file is imported and the work should start the app don't respond anymore.
After two days of installing, registring, unistalling and registry cleaning (and yes, getting a bit crazy) I've finally found this thread which seemed to be helpful.
So, I tried to update my video and audio drivers, but just got a message I have a newest version for all of them. So I decided to uninstall a driver for my graphics (Intel R HD Graphics Family) and rebooted the ntb. The resolution was terrible, but I was still able to try the app. And yes, Video Convertor suddenly worked.
BUT - graphics adapter with no driver is useless so I downoladed and installed one again (actualy the system did it automatically), then reboot and then - Video Converter again freezing :((
So, it seems that the driver for my graphics adapter makes troubles when working with AVS4YOU apps but have no idea how to deal with it.
Thanks for any suggestion !!!!
David
