First, we apologize for the issue and frustration...
For Rebellion HTTPSendRequest activation errors, open up Internet Explorer (any page is fine) and try activating the game again with it open.
For those that have run into Max Activation as a result of repeated attempts after getting the error, please try again as that has been addressed as well.
For others with mini dump issues, please see this KB article here:
If these fail, please place a ticket here: https://esupport.stardock.com/index.php?/Tickets/Submit
If you have already placed a ticket, and one of the solutions above worked, please reply to the email \ ticket that it has been resolved so we can readily work on the ones that have remaining issues.
Again, sorry for the trouble...
