You can try setting both the game's and Steam's executable to always run as an administrator.

To do that, follow these instructions:
1. Completely close out of Steam and make sure that it is not running
2. Go the game's launch folder (C:\Program Files (x86)Steam\SteamApps\common\Ascend Hand of Kul\bin)
3. Right-click on Game.exe and proceed to "Properties"
4. Go to the "Compatibility" tab at the top and then check the box near the bottom of the window that says "Run this program as an administrator"
5. Then click "Apply" and then "OK"
6. Now do the same for Steam by going to Steam's launch folder (C:\Program Files (x86)Steam) and locating Steam.exe)
7. Repeat steps 2, 3, and 4 for Steam.exe
8. Run Steam and then launch Ascend through it
