Had the same problem after loading V4.10 on two separate machines (both laptops). Eventually uninstalled 4.10 and the MSV patch from Sony and reinstalled 4.01 which I had a copy saved. Also reinstalled the Sony patch for MSV. Works perfectly again. So must be the new version. I had tried the same file before the upgrade and ran well on 4.01 and 4.06 and 4.09 running on PC versions; just would not run on 4.10. So am thinking a software bug. Also 4.10 bogged down the whole drive as kept loading and loading for hours when the same file loaded in the lesser versions in minutes.
