A few months ago I installed VS Express 2013 for Desktop. After about 4 days I got the pop up screen on start up saying my license has expired, tried the link to "check for an updated license", got the response saying "downloaded license insufficient" and I can only exit.
Back then I gave up after a few days and abandoned the project I wanted to do. Now I have another project that requires VS that I would like to do and I really need to get it working.
I still have the same messages. I tried the time zone workaround with no different result. And there doesn't seem to be an issue with signing in, it shows me signed in just fine.
