I don't have the DVD as he threw the upgrade in at no charge. But in the meantime, he just called, and it turns out he left the admin password blank on purpose and is sure that will work. I'm having a beer before I try it..
First of all, I'm glad I could even reach him - he works at a PC place and works on his own on the side. Plus, he was really helpful the last time but that was quite a while ago. If blank won't go through as a password, he'll help, I'm sure, even if only giving me the dvd to do what you were saying.
Thanks for responding, parados, appreciate it.
