Tried to download SP3 update. This failed and then my problems started.XL won't open without the message "trying to configure office XP with front page" this fails with the message "the feature you are trying to use is on a network resource that is unavailible". Its looking for "installation package PROPLUS.MSI" which cannot be found. Now any download for office pro xp fails with same messages. Cannot use system restore either. The PC came loaded so I do not have any discs. My PC is not networked. I have tried all the MS support suggestions without success. Can any of you boffins help?
