Hi Cy,
I hope you still have your Office 2000 installed on your computer (by
installing the trial version of 2003 into a totally new directory, and even
separate drive). If so, just use Control Panel, Add or Remove Programs to
uninstall the 2003 version. If you overwrote your 2000 or uninstalled it to
install the 2003 trial, then you need to try the System Restore, or do a
total uninstall of 2003 and then reinstall 2000, as well as do all the
updates from microsoft.com...
If your OS is Windows XP, you can use System Restore to go back to a time
before you installed the 2003. You may need to insert your 2000 discs so
have them handy.
But first, be sure to explore
http://support.microsoft.com/default.aspx?scid=fh;EN-US;ofw (including the
Knowledge Base) for input on going back after using the trial version...
usually they have a Readme.txt file with the trial version that explains how
to install and remove it (look for it in the Microsoft 2003 directory under
Programs). As you can tell, I'm not so smart on this stuff so I hope someone
else comes in with better pinpoint advice, whereas I'm in the ballpark but
probably left field.
If you click START|ALL PROGRAMS|ACCESSORIES|SYSTEM TOOLS|SYSTEM RESTORE you
can choose a date before you installed 2003. You won't lose any of your data
but you may not be able to use that which you created and saved under 2003.
Good luck and let us know how it turns out.
