#7 Crashed & unable to restart / upgrade

[Saleem Althaf]

Running version 0.62 on Win XP Pro SP2, Sun Java VM 1.5.10, 1 GB RAM, P4-3 GHz.
40k messages, was running well until a few days ago when I needed to use Ssytem Restore to return to a previous state. Now refuses to run.

Error messages below:

Have tried re-installing 0.63, Java VM but no luck.

What have I messed up? Thanks
