Iv'e heard your problem seems to happen when your NORMAL.DOT file gets corrupt....so you can try and rename the NORMAL.DOT file to NORMAL.OLD
Whether this will work....i don't know,iv'e not tried it myself but i saw this same problem in a thread and it seemed to work,but the only problem is i can't remember where i saw the thread, but this link will take you to a lot of other solution sites...
