what's wrong?!?

My mogul wouldn't let me download any cab files, because it said that "there wasn't enough space left" (even though there was a brand new 2 gb sd card in the device). So I deviced to connect my device to my PC and reflash the htc rom, which would hard-reset my device. But when I connect my device to the PC via the USB cord, ActiveSync recognizes the device but says:

"Synchronization cannot be completed successfully. Reconnect your device and try again. If the problem persists, see the Microsoft Activesync Troubleshooter in Microsoft ActiveSync help on your desktop computer."
What is happening?!?! If I can't reflash the rom, how can I hard reset? I've tried this, but it doesn't work. Can anyone help??
