coh.exe application error

Hi,

i have recently started getting coh.exe Application error message frequently flagged up and i wish to fix this perminantly.

 

The error states that 'The instruction at "0x77c01ddc" referenced memory at "0x013a058c". The memory could not be "read". The error then gives one the usual options to cancel/debug or terminate the program using the 'OK or Cancel' buttions.

 

How do i fix this???
