I'm having a problem with Hotsynching.

I just tried using a USB serial adapter with my charging cradle (since the serial port on my CPU became loose and stopped working), but cannot seem to establish a connection bewteen my computer and my handheld. I was able to Hotsynch before with this cradle, so know that's not the problem.

I installed the adapter and the accompanying drivers properly, so don't think that's the problem either. And, the adapter (made by Belkin) states that it is universally compatible.

Can anyone help me? Thanks.
