How do I take off the "Read Only" thing?

[Mex]

Please help me because I cant type anything or do anything in Microsoft Word
2003 and at the bottom when I try to type it says "This modification is not
allowed because the document is locked" and I dont know what I did wrong to
lock the document.

Sounds like "reduced functionality mode" either because you have not
activated your Office software, or because you have an expired trial version
of Office 2003. What happens if you start Word and click on Help | Activate
Product? If the software has been activated, you will get a message that
says so. If the software needs to be activated, the Activation Wizard will
start. If you have expired trial version, you will be prompted to enter a
product key, and you may see an option to purchase a product key online from
Microsoft.
