Hello, I am new to this forum and I have a few questions:

-First of all is LimeWire Legal? I heard that it was illegal and that you could be fined thousands of dollars for using it.

-Is LimeWire better or FrostWire?

-I have LimeWire but something happened and now I get these little pop-ups saying that LimeWire is corrupted and that I have to run the chkdsk utility. What is that and how do I do it? It made me lose all of my saved files and anything that I try to download only loads to 99% and not 100%

Please help.
Thank you. -Shadowbeast316
