[users] crash

[Maria Weissenberg]

Dear Sirs,
I've downloaded -as a suggestion of my own computer- the OpenOffice Org 2.3 and 
since then, my computer suffers from crashes, the screen gets blue and I have 
to reiniciate the whole thing, many times loosing what I was working on...
I've tried to remove this program -maybe I've downloaded it with errors, and 
would like to download it again- but it's impossible.
What can I don? How can I remove it?
I'd be very grateful if you can help me.
Best regards,
Maria
