Sometimes I have no problem with it. I have had to reinstall Aquascape and a couple of the Fishdoms a few times to get them working. Right now, the problem is they won't open. Can't run as admin, either. I click to open, the "working" icon runs, then it quits. The Game Top browser window opens as if I had closed the program myself. This happens randomly with other games, also. Running Win 10.
