Mark changes the Nbar and Nstar for f0bar and f0star

Dear all,
I'm using Mark 8.0 on a Windows server 2008, and when ever I start mark and run any model it goes flawlessly. The problem arises when I retrieve any model, and then opening the Parameter index Chart it will change all the names of Nbar and Nstar for f0bar and f0star. After that I can't run any model have to exit Mark and restart it, and then instead retrieving any model I have to start build it again manually. I have no idea why this is happening, but I guess it will be good to post if anybody else is having the same problem. Anyway to fix it? I'm contacting IT to reinstall Mark8.0, but perhaps will be better to go back to 7.x?
Cheers,
