SAV MSE - It's a Mystery
Despite a clear desire to escape from these things it can be difficult. Todays installment brought a new error: "Please Insert Disk 1". Despite all my best attempts, I could not divine what disk '1' was/is.
After much searching, I finally found a link reporting that this bug was fixed - ??? - and it was related to "Installing MSE gateway from removable media". Since I couldn't find a download link, or other way to update, I copied the entire install directory to my c:\ drive, and viola! It works. Yay!
