I had this problem and here is what the support desk sent me. It worked:
"This problem may be caused by the enforcement of DEP security. This may have been caused by a windows update. Here's what to do:
1. Click Start, click Run, type sysdm.cpl, and then click OK.
2. Click the Advanced tab, click Performance, and then click Settings.
3. In Performance Options, click the Data Execution Prevention tab, and
then click Add.
4. In the Open dialog box, locate and then click the program (crd5.exe).
5. Click Open, click Apply, and then click OK. When you are prompted to restart your computer, click OK."
They also said that the latest build has been set to have tolerance for DEP so I downloaded and installed that.
