If, as you say, you USED to run the LimeWire Program with no problem, this should be your first clue. Sometime since you installed the program and the first BSD you did SOMETHING. Rack your brain. Did you install a new driver or piece of hardware. Did you upgrade an installation from, maybe, the Windows update site causing a conflict. Somewhere, somehow, you made a change in the Windows Installation. Does Win2000 support Go Back or Restore??
