On my system, after uploading 7.075, and then clicking apply, the ASG (being upgraded from 7.011) did not recognize that the file had been uploaded, even though the progress bar went to 100%, etc.
I logged off and back on, still no evidence that the system recognized an upgrade file had been uploaded.
Uploaded a second time, and this time it appeared and was able to run the up2date without any further problems.
