erros during LaTex run...

[Kathryn Wotton]

Hey, 
Ive had a few problems with viewing a preview of any documents ive done in
klyx, sometimes when I do file -> Preview -> view DVI, it comes up with an
alert message saying "there were errors during the LaTex run. One error
detected. You should try to fix it."
I have no idea what the problem is and it just comes up with an error box
somewhere in the document!
Thanks in advance!
