Hi spyrofate and Welcome to the Gnutella Forums.
To be Honest with you, you Won't get Any response from the LW devs here. I will give you the site link that May help you out, but Don't count on it. There are a few LW devs that may or maynot respond to you here.
LimeWire Forums
It sounds like you may be experiancing either Fake or Corrupt files and if this is the case, LW wouldn't be able to help you anyway. That would be a Network Issue.
