hi,

tried to boot up U5 - Dos Screen came on and off and then nothing happened (back to Windows Desktop screen)

Tried to boot up U6 - Went to Dos mode and DOSBOX intro and then freezed.

Please help? Thanks!

Try different Graphic options e.g. ddraw in the Setup programm you can find in your start menu.

Also try to run as administrator if you have installed it inside Program Files folder. And if running Vista or Win7

I was literally just having this same problem and ran as administrator, works like a charm now, thanks!
