The unhandled exeption error is still present. I tried reinstalling the catalyst drivers but it didn't help.
Please post the full error again. It has the version number in it. That will allow me to see if you are running the right version or if it is a different error. I know that the issue with CHNCoin is fixed in that build I linked so if you are still having a crash it is either a different crash or you are not using that build.
