With the 1.05 patch on Steam, we've received a few reports from people saying they are receiving the following error:

Data folder not found: There should be 'PillarsOfEternity_Data' folder next to the executable

To fix this:

1. Open Steam and click on the Library tab.
2. Find Pillars of Eternity in your games list along the left, right-click it, and choose Properties.
3. Click the Local Files tab and click the Browse Local Files... button.
4. You should see a "EmptySteamDepot" folder. Right-click it, and choose Rename.
5. Rename the folder to "PillarsOfEternity_Data".
6. Run the game again and it should work now.

If you don't see an EmptySteamDepot folder, we recommend reinstalling the game.
