Note: Build 371 works. The updated version, 511 does not, in any compatibility mode (Windows7, any SP of Vista, etc.). After uninstalling build 511 (and deleting all Sony folders and powering down) I re-installed the older version (build 371), which worked again. I will be refusing update notices and sticking to this version, until we can get this figured out.
If you can get an older version, attempt that. You may want to get a hold of Sony to see if you can get a lower build. If you purchased your current build, they should have no problem getting you an older version (build).
