HELP!!!!

[Flavius]

As you can see from log you are redirected to new profile C:\Users\TEMP.Dave-PC.001 instead your old C:\Users\Dave

Because Dave is the only one admin account before start fix,create new admin account and from this new account you'll repair the old one or boot into safe mode and login into build-in admin account.

following these instructions:
User Profile Error - Logged on with a Temporary Profile - Vista Forums

A temporary profile is loaded after you log on to a Windows Vista-based system

from these articles:

1 Log on to the new admin account
2 Back up all data from the original profile this means backup data from C:\Users\Dave
,next remove C:\Users\Dave folder
3.Open regedit and remove key HKEY_LOCALE_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-273225884-3958399719-2952842563-1001.bak

4.Logoff from the system and LogOn again,your profile will be recreated
