Try checking your video drivers on steam.
Okay. then try right clicking on Sins, hit properties, then go to local files, and click the Verify Integrity of Game Cache button.
If that doesn't find any installation problems, also try going to your steamapp folder and find the "Sins of a Solar Empire Rebellion Dev.exe" file. Run that and see if it works or if you get any error messages.
