I suspect that you license doe not allow you to run the subscription edition Quartus II 10.1 version. If you open the license file, there should be a feature line something like:
FEATURE quartus alterad 2010.06 permanent ....
This is the license feature for Quartus II software. The date field, in this case 2010.06 (June 2010), indicates the date in which you can no longer get updates. So, for example, here it indicates that you can get updates to the software up to June 2010, and subscription release of software after this can not be run, without getting an updated license.
10.1 was release this month.
You mentioned web edition for the Quatus II 7.1, but I suspect you installed the subscription edition.
