Visual Assist build 2048 was issued on the heels of build 2047 in order to fix a regression in the latter. Using build 2047, a VA Snippet that includes a GUID reserved string expands the string to zeros instead of a valid GUID.
If you have build 2047 and use VA Snippets to create your GUIDs, you should install build 2048. Visual Assist build 2048 requires software maintenance through 2014.09.22.
Learn about GUIDs in VA Snippets, or download the installer.
