ACR 11.0 Crashing

Hi,

Since I completed the new CC update, I have not been able to open any raw files. I am using a Nikon 700 and did not have any issues before this update. I can load JPEGs and PSD files, etc, but raws are not working at all. I have tried to open a few JPEGs as raw files and "Could not complete your request because the file-format module cannot parse the file" error is coming up. Please help. I'd really like to start working on my photos again. Thanks in advance
