I upgraded my Java JRE from 1.3.1 to 1.4.2_11. After doing this I rebooted my machine and I get to the Windows XP splash screen with the the progress bar and it never leaves this screen.
I rebooted in safe mode, went to SYstem recovery and selected a snapshot from the previous day. The recovery was apparently successful but a reboot just got stuck at the same screen as before.
I've tried recovering to an older snap with the same results.
How can I correct this problem?
