MapleRoyals can't be opened after updating to macOS Sierra

Hi guys! So I've just updated my mac to Sierra and MapleRoyals wouldn't open (clicked but nothing happened, could only force quit). So I decided to reinstall it.
After the first reinstall I got an error saying it couldn't run because it was a read-only file, which it wasn't so I deleted and downloaded it again. Now I get an error saying ''%@'' can't be found, the application ''MapleRoyals Client'' can't be opened (see below). Deleted and downloaded it again but I still get the same message. Helppp!

 

Update: Redownloaded and I'm getting this error again:

 

Would be great if we could get a guide on how to run MapleRoyals from a Sierra machine if anyone found out how to get it to work.

 

I have same problem here..............
Any solution for this.....?!
