I liked a lot Loom 2. I did some few demoes with it. Anyway, I would purchase it again (and all AIR instruments) if it weren't for the ilok.
The best way to deal with technical problems is IMO writing them here in the forum or ask Simon directly for help (very helpful manager that usually resolves all problems fast). I have a very good experience more than one time contacting him. I can't say the same a out iLok though
