Try running it in demo mode. We specifically made the demo mode warning time out after 30 seconds with installations in mind.
The reason I’m suggesting demo mode is that you said it ran fine for two weeks and then started having problems. Licenses (depending on the type) will try to check in online every two weeks, so by going with demo mode we can eliminate that check as a possible cause of your issues. (To be clear, I don’t think it is the problem, but fewer variables is always better when it comes to isolating issues with no clear source.)
[Edit: Though I suppose if it’s not the source of the issue, you’ll have a 30-second dialog come up whenever Isadora has to be brought back up… hmmm…]
