before you toss computers ...find a computer geek that can let you use it just for your software....that way...they can delete what you don't need for it and then get another just for your other use.
they never tell you these things up front..ggrrrrr makes me so mad.
sorry for your bad luck....But I would also reserach the name of the pred of the company and send him a personal letter and give him what for.But if you want something done don't fool round with the little people.
