Anyone know how to do what I need to do?

First of all, all I have is a copy of the old hard drive on a DVD disk. I cannot export the files, and the Address Book has an extension OE6 with SP1 doesn't recognize. When I use the import utility in OE, it says that another application is using the messages and it cannot import them.

Any suggestions? Installing Netscape is not an option, as the problem was not enough computer to run Netscape 7 properly.
