I did a cursory look at the forum and didn't see this problem. I installed v1.5.2 and did the requested reboot. Now I can't log in to my system. I click on my username and type in my password, and the system logs me in and then immediately logs me out. This happens repeatedly. I have tried virtually all boot modes under the f8 menu: safe mode, debugging mode, everything. (OS is XP Pro, and I think it is completely updated--it updates automatically). The behavior is always the same for either my regular account or the admin account. It logs in and immediately logs out. Any suggestions? I REALLY don't want to reinstall the OS.
