I loaded Office 2003 on my laptop after i had already
loaded it on my desktop. When i tried to register it it
said that i can't load it on more than one system. Then i
tried to go revert back to Office XP and now Outlook says
it can't open my "information store" file. Is there a way
to convert my OST file from outlook 2003 back to outlook
XP?

OST or PST? There's a big difference - OST files are used for offline access
to your Exchange mailbox. PST files are used mainly by standalone
(non-Exchange) Outlook.

Did you create a new PST file in Outlook 2003 using the new unicode format
(larger file size)? If so, you will need to open that file in Outlook 2003
on another computer, create a new "old" style PST file, and copy/import the
data into the new PST if you want to use it in Outlook 2002/prior versions.

No, once you change your profile with an .ost file, it is "toast." Why
couldn't you activate Outlook on your laptop? Did you try the telephone
method?
