<<Edit: I saw your post above after posting this.>>
The second message may be related to the first. The conventional wisdom would be to fix one thing at a time.
After getting these messages, do you have a command prompt? To test, type "ls" (no quotes) and see if you get a response. If so, enter "ls -al ~ | grep dmrc" You should see something like this for .dmrc:
-rwx--x--x 1 mherring mherring 26 Jan 18 10:18 .dmrc*
By any chance, during installation, did you tell it to mount /home on the FAT32 partition? That could be the issue since FAT32 does not allow setting permissions the way the Linux filesystems do.
to check, enter "mount" and post the results here.
If you don't have a command prompt, then try single-user mode as suggested earlier.
