Temporary User Account gone with all my files. Please Hlp.

Due to issues I dont quite understand Windows XP didnt letme sign in onto my normal account and so a new temp account was created. Being the genius I am I moved all the files frm my Admin-powered account (David) to the temporary account. When I logged in again the temporary account was gone along with all my files. I could sense the dark clouds gathering above me. Please help me, some of those files are of extreme importance. Ive been up all night trying to locate it but the only thing I seem to have been able to locate are unhealthy amounts of caffeine. Thanks to anyone that can help.

Once again, help.
