Diamond does not detect computer

[battousaix]

I have a htc diamond in which i just flashed to the Ultra Lite windows 6.5 rom. I've been using Juicy and Groove roms usually and had no problems. When I flashed the ultra lite rom it worked fine at first until it froze one time. So i took out the battery and resetted it. It then reflashed the rom when i turned it on (it said tap here to start configuring your device, etc...). So all my contacts, etc are now gone so I need to connect the phone to my computer so I can sync it with Outlook. However, it does not detect the sync center and it only charges. Can someone tell me what's wrong please?
