Query: Britannica 2000 is problematic

At first, Britannica 2000 CD worked reasonably well. However, now, it does not work at all. It hangs during application start-up. I suspect it has a problem sharing one or more DLLs with other applications, since there was an update to Britannica 1999 to resolve a similar problem. The excellent content is of NO value if you can't access it (and I can't).
