I Googled this problem and saw many talk about it, but no one come up with a concrete solution. Some people said the problem went away if they just redownloaded the tracks they were having problems with, but others had the same problem with you were suddenly *everything* was having problems.

I would do as inside-eye suggested and download Traders Little Helper and see if your problems go away then. TLH is an all-in-one program for the PC that will decompress your shn, flac, and ape files and it has shntool built in also. It's the only program you will need for all your lossless compression/decompression. The link is in our Software FAQ.
