If you have the 3.01 updater, your instances of C exception should be much reduced - but I found that a few items of clothing that were meant for Poser 4 would still cause it, and never did find out the reason. The easiest way to fix it (in my opinion) is to create a new CR2. This is relatively easy for Poser 3 since you don't need to worry about conforming, just posability. I used to make a master CR2 from the appropriate figure (see link), then make it refer to the clothing obj file.
