Flow simulation crashes after resetting computational domain

Hello,

I am trying to solve a Flow Analysis by using Flow Simulation in Solidworks 2013.

All of a sudden Solidworks keep crashing after the prompt:

'The geometry of the model or project settings have been changed. Do you want to reset the computatutional domain?'

It doesn't matter if I choose 'yes' or 'no'. Both choices will make Solidworks crash.

Due to this problem I am unable to start up the Flow Simulation add-in for this assembly.

Does somebody have an answer for this? Maybe to unable the prompt showing up?

Thanks!
