Why is it that when I try to download a GruntWorx job, a GW Job Downloader screen appears with a long error list?
You're referring to an error appearing on the GWJobDownloader screen that begins with:
Error downloading job: Exception of type 'System.OutOfMemoryException' was thrown.
Reboot your computer, then immediately complete the download. This error is caused by insufficient memory. You may have a program open or running in the background that uses a lot of memory, or there may be some other condition that produces the same result. Generally, this error is not directly related to the size of the GruntWorx download.
