Spent the last few evenings recreating a build environment for the Windows version of the coin, finding capable packages, etc.  Did upgrade to 64-bit.

Having one problem with the new code and wondering if this rings a familiar bell with anyone:

The new executable claims the old wallet is corrupt.  It works fine is allowed to create a new wallet, and the old wallet works fine with the old executable.  Tried 32 & 64 bit versions.  Tried db5.3 as well as the original db4.8 - no difference.

Not really interested in moving all my private keys, would rather figure out whats wrong.

I DO NOT have this problem with the Linux version, the code was completely compatible there.

This isn't hyper critical, but would be nice to get fixed.  Other than going to 64-bit mode, the only other change is additional checkpoint records and a bump in the protocol (which I used to track adoption of wallet packages).
