Goback crushed and won't respond to gb_prog /u and ANYTHING

Goback crushed. I can't reboot windows XP. I reboot with Norton Bootable Recovery Tool,  tried option 1 to Unhook Norton GoBack from MBR and option 2 to fix MBR. Tried command gb_prog /u. Nothing worked. 

I keep getting this message: GoBack Internal Error - Failure Code: gb_genlog(181)

I ran windows diagnostic disk. All hardware past test. 

Please help me!!!  Maybe hang myself will work? :)
