Emulator stoped working on Windows 7 (64bit)

Emulator on my computer suddenly stoped working. Only Channels works even that from 0 to 10% only and HOLD and FMODE works. It works perfectly on my other computer running Windows XP though.

Thanks for your help.

which emulator bud? as both the 7e and 10 emulators are working fine on my win7 64bit desktop

I have tried both V4.01 and 5. They do not work on this computer.

for which transmitter emulator? all transmitters have their own emulator so i need to know which one you are trying to see if i can replicate the issue
