Slow downloads and few search results

[clfourmo61]

I recently purchased LimewirePro version 4.18.6 and am running Vista home basic service pack 1 32 bit operating system. Before buying limewirepro I had basic and had very few if any problems. Now my downloads are so slow it is getting to the point of getting help or getting a refund. My download speeds are anywhere from 1 KB to 40 KBs.With basic I had speeds from 150 KBs and up. Also I get very few search results. Again, alot less than when I had limewire basic. Not to mention all the corrupted files that come through. OMG! If I can get help with making the download speeds faster I would appreciate it. By the way, my computer has 78.2 GB free space of 140 GB. My ISP is At&T. Also I am running Norton Antivirus and firewall and no there is no wall covering the blue world icon in the bottom left of the limewire platform. I hope this is enough info for you if not please let me know.
Thank you
