In what situation is it dropping frames?
You did not open a version 1 project in version 10, did you? That will most certainly corrupt the project.
You need to provide operating system and hardware details
These questions below may be for a different product... but the information you need to supply is the same, for the products you use

Hope this helps

A couple of thoughts on situations, that can drop Frames:
Dirty heads in camera - a high-quality cleaning tape may fix this
Too slow a connection to the Capture HDD, or the drive too slow - SATA should not be an issue, but is that WD HDD 5400 RPM or 7200 RPM or faster?
Real-time, active-scanning anti-virus, or anti-malware programs - if you have such, Capture again, with those turned OFF
Others might have a few more ideas for you.
So you're capturing from a tape-based miniDV camcorder, right? Again, the more details you can provide, the more likely we can help.
Have you ensured that you've got no annoying background processes interferring with your capture? Norton 360, Windows Indexing, etc.
Also, try capturing with the free program Win DV and see if you get the same dropped frame results.
