Connection Problem with Musicmatch

I believe my problem is Windows related since it is affecting different
programs.

I cannot get a connection when I try to play On Demand tracks on Musicmatch.
The song comes up, but won't play. Other songs will play however.

In Morpheus and Limewire, the connection is so slow (if at all) that it
barely works. Morpheus shows the sign "Waiting for internet connection."

I have uninstalled and re-installed: Musicmatch, Limewire, Morpheus,
Anti-virus. I have also tried using these programs with Windows firewall OFF
and antivirus OFF, but still nothing.

The internet works fine though. I am using a wireless connection. This
problem just started happening last week, and the programs haven't worked
right since.

Could this be a deep seeded connection issue? Any help? Musicmatch, HP and
Symantec have been of no help. THANKS.
