Crashing again when loading customers disc

[G-Force]

I am using 3.10, and when importing from a customers disc, hoster will either freeze up or my pc will completely lock up. The disc this happens with is an original top tunes multisession disc, and up until saturday would onlt screw up when trying to read the last track. But Saturday night, the customer chose another song offthat disc, and it also froze up, even tho I had gotten at least one good song off that disc that night. I thought we had all these problems taken care of with 3.08, but the problem has returned. Help! I cannot run a show with a pc thats gonna freeze up on me and have to reboot everynight. This is a MAJOR problem.
