Does that mean just sharing programs or any program at all?

Here's a test. Since you are here in the BearShare forums try BearShare.
It is different enough from LimeWire that it just might work for you.

BearShare Lite 5.1.0.27

If this Lite version works and you want to upgrade to the powerful beta
version that came out just before, I'll help you set it up. The difference is
that the beta can download files faster and can be forced into ultrapeer mode,
which raises your searching connections from 2 to 70. :yahoo:

If it doesn't work you do have a serious problem, and we'll have to try some diagnostics.
