HELP! Bought Pro and it all went wrong...

[06TC_OWNER]

I purchased pro today and decided to give it a spin. I had just ran the free version and searched on a topic, and downloaded 12 4 meg files in no time flat (I was impressed as I had never tested limewire with my new 12meg connection). Then I decided to purchase pro to see if the hype was true, so I ran that, searched, and got a ton of results (faster and much more then standard version), BUT... I clicked on about 6 or 7 files just to see how long it would take, and it took a long time saying "connecting," then after a while it said "need more sources." I figured this was odd as the connection # was in the 100s, but I figured I'd give it another chance, so I grabbed the same 4 meg files from this morning, but those also said "connecting" and then "needs more sources." After about 15 minutes of this, I came to the conclusion that something has seriously gone wrong with my upgrade to pro - EVERYTHING says "connecting" and then "need more sources." I have tried resetting the pc, etc, but I am not getting anywhere! According to the app, I have a "Turbo Charged Connection," but it seems to only allow me to search. I tried opening a port and setting the port to that, and I also tried the default pnp, but I think if that was the case, I would get a firewall warning...

HELP?
