To answer the original question, you should add Crysis2.exe to the Data Execution Protection. Go to your My Computer and right click it and click on Properties. Then on the left hand corner, click Advanced system settings. Then go to Performance and click Settings. Then go to the Data Execution Protection tab and add it to your DEP exception list.
Thank me if this helps. Good luck!
As for Nazgul11, try the same thing I explained above. Good luck to you as well!
