I can't reproduce this in r1636 on Win Vista. This might have been fixed already. So, stay tuned for the new prerelease so you can test it again (coming soon).
I tested with the latest prerelease r1644 (download at http://prereleases.musescore.org/windows/ ) and I can open the score without problems. I'll mark this issue as fixed. Reopen if you still have problems.
