Battlfield Vietnam SafeDisk Problem

This is not a copying problem. I was hoping some one could help me. I installed BFV and run BFV from the retail disk but the game crashes on map changes and any time I try to launch after the initial disk insert. I disabled my virtual drives but it still didn’t work. I have had this working before; I don’t know what went wrong. If you’ve played BFV you know that it reads for the disk on map changes and at start up (like most games) and the game uses SafeDisk 2.9. Its like there is something messed up with my SD verification driver or something, I don’t know. I have Battlefield 1942 and that uses SD, works just fine. Any suggestions besides reinstalling? Thanks.
