With "All addon are in Trial mode", do you mean then are in Trial ? "Trial mode", means you do see the scenery perfectly, but only for 5 minutes at a time.
If, instead, you don't see the scenery at all, it's NOT "Trial mode", it's "software not running", which is a completely different issue so, please, clarify.
Last time this happened it was the Couati program that was giving me grief.
No, it didn't. It was another program (antivirus, usually) or missing runtimes libraries that should be on your system, which caused grief TO Couatl, not the other way around. It's possible the same it's happening now, which would result in the program not starting because of these issues on your system. Do you have the Couatl menu visible under the "Addons" menu ?
