This is maddening. CC4 upgraded to CC4.1 and when i went to use it, it had a watermark all over it. CC4 was watermark free because it was all paid assets etc. I uninstalled CC4.1 and tried to reinstall CC4. No go. It stops downloading at 2 GB and won't go further. There's nothing wrong with my high speed internet connection.
I turned off security software and managed to download it. I've downloaded 8 GB of the same file - good thing I have high speed connection and a large bandwidth to play with. My other problem is that there is a watermark and I can't get rid of it no matter what I do. I have reactivated all the items I've purchased but it still persists. 
Can someone help me understand this issue?
