If anyone is having trouble running the game for longer than a minute & you've been using world builder & keeping the saved .sgb files / folders in the games' main folder that it requires for you to edit them (C:\Program Files (x86)\steam\SteamApps\common\Company of Heroes 2\CoH2\Data\Scenarios\MP\), try moving them out of there when you run coh2. If that doesn't work, you can do what I had to do which is delete all traces of coh 2 like replied to me on official site but kept my home made .sga files to re-extract for editing...
"Start by uninstalling Company of Heroes 2 through Steam:
Right-click on Company of Heroes 2 and select “Delete Local Content…”
Next, delete Company of Heroes 2 from my Documents/My Games:
Start Menu > Documents > My Games > Company of Heroes 2
Delete Company of Heroes 2
Windows also likes to hide files in the appdata folder under you user profile. To clear these out make your hidden folders visible and delete everything in this folder:
C:\Users\your user name\AppData\Temp\
Then delete everything related to the game in this folder:
C:\Users\your user name\AppData\Local\VirtualStore\Program Files\
C:\Users\your user name\AppData\Settings\
When completed please restart your computer and try the installation again.

and then it should work. Doing just the delete local content & re-installing it in steam alone wasn't enough. DO NOT then copy back over any older .sgb folders... if you want to keep editing the files, just extract the .sga (that hopefully you do have) with the archive.exe file again
Anyways, there's now 21 maps up & more on the way...
