I'm having the same problem. I can find files with 35+ people available with a file, but it never gets above 3kbps at any give time. I've erased all my old files, looked for a preferences folder, took down my firewall completely, selected the advanced features that take down the extra P2P stuff, shut down every other program on my computer, limited the upload speeds, limited the number of downloads....and I can't think of what else. Is there anything else I should do? If not-then how do I get my old version back?? At least it was working
