With regards to the IDE, the problem is that Windows allows up to 255 COM ports, and with the proliferation of USB COM ports, it's very easy to have high numbered ports. The older software only allowed ports up to COM8, if I recall. The current IDE does a very extensive search for COM ports, but clearly couldn't find the ones on your system for some reason. Is this the USB COM port you're using?

It's the final release version 2.2 of the IDE.
