Mdlvis problem?

Level 3
Apr 18, 2011
Today I was working on the skin of my new models, and when I finished, I had to change the UV map for it to look right. When I went into Mdlvis to modify the UV map, I got an access violation error. At first, I thought it was something wrong with the model, (it seems every model I try to make has something wrong with it) but I then put the unmodified texture back in, and I could the UV map fine. I change the texture, and it didn't work in Mdlvis, but I can view it in Magos. Any ideas on what is wrong?
