Word unexpectedly quitting

[Elije]

Hi

My word application keeps unexpectedly quitting. Sometimes it will do it every ten minutes or so, sometimes not for a week but the problem has not gone away.

The first part of the error message says this (if that helps) -

PID: 196
Thread: Unknown

Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000084

I hope someone has some advice as I am in the middle of writing a dissertation and this problem is not good!

Thanks
