Thank you very much! I tried what you suggested and it worked like a charm. It's also good to see I wasn't the only one who had experienced this before.
After a couple of hours with my recovered OS, I decided to reformat it anyways. I currently have ZAP 7.0.362.000 installed and working and I've already recieved the message to upgrade to 8.0.
Seeing as how I still run SP2 at the moment, I don't think I should take the upgrade. Am I correct?
Any advice would be welcome
and once again, thank you for the earlier help
