Problems launching ArtRage through Steam
If you are having problems running the Steam version of ArtRage, then there are a couple of common issues that are likely to be to blame.
1. Verify the local file cache:
Locate ArtRage in the Library (under ‘All Software’, ‘All Games’ is selected by default and it’s not listed there). Right click it and select Properties, then select the Local Files tab. On the Local Files page, click ‘Verify Integrity of Application Cache’.
That should check to make sure that the files are all valid.
2. Try turning off the Steam Community options for the app:
Sometimes launching from Steam (which creates a virtual shared disk for their SteamCloud system) has been known to cause crashes in a variety of apps.
To turn this off for ArtRage…
Locate ArtRage in the Library as above, right click it and select Properties. On the General page, turn off ‘Enable Steam Community In-Game’. This tells Steam not to try launching special services when the app is launched.
If you are still having problems, try launching ArtRage without Steam.
