My Upload Speed Slowed Way Down ???

[MusicMan_59]

I've had Limewire for 3 years. I used to allow 20 upload slots & my upload bandwidth usage would go up to 3 to 5 hundred Kbs/s. A few weeks ago while on Limewire, I noticed that over half of uploads said "transfer interrupted" I knew something was wrong because in 3 years I'd never seen that on more than 10% of uploads. I checked my Upload Bandwidth settings, it was still at unlimited. I checked my internet speed, it was the same 750kbs/s. I ran every diagnostic test I have on my computer. I checked and double checked all my settings and my computer.......nothing. I re-downloaded Limewire...still nothing. I had to reduce my slots to 3 because my total upload bandwidth will only reach as high as 20kbs/s total now. If 1 slot is in use they can use up to 20 kbs/s or less. If 2 slots are being used they split the 20kbs/s, and so on, but it won't go above 20kbs/s total. What ever the problem is, it hasn't effected my download speed. I can still run it up to 4 or 5 hundred kbs/s, with enough downloads going at the same time. I'm totally confussed & frustrated . I hate it because I have a lot of files and I like to share. Can somebody help me ?
