Mel can you please try a reinstall of the SWE. If that doesn't help please report to your VAR.
I did do a reinstall of SWE...that didn't work, but being a new install for what ever reason SWE wasn't directed to the directory when my files are located....once the correct path was set it worked. My guess is SWE timed out searching the complete machine? Don't know. Again thanks for your response.
