I don't know why you're getting that particular error & cannot help with it, sorry.
But I'd say that version 3 is a bit old & you may want to go in for something newer. If cost is a constraint get Norton SystemWorks PRO 2003 from here for £5-10 - click here=. The PRO version contains Norton Ghost which is similar to Drive Image. Make sure before buying that the disk is a genuine Symantec product (& not a blank-faced copy) & get only the PRO version as the standard NSW doesn't contain Ghost.
