OE version 6 often crashes

Hi experts,
I got the last time OE crashed. This happens about every couple of days. OE version is version 6. Should I somehow uninstall it and then download it from microsoft.com and re-install it? I am waiting for your suggestion. Thanks.

Error Message: The exception unknown software exception (0xc0000008) occurred in the application at location 0x7c964ed1.
