To turn off Steam Cloud for LH:
1) Start Steam, click on Library
2) Left hand side where your games are listed, right click on FE: LH, click Properties
3) Under Updates tab, untick the Enable Steam CLoud checkbox
I suggest you also try and "Verify Integrity of Game Cache". Under the Properties again, go to the Local Files tab.... click the Verify button.
If none of that helps, check the how to report and issue sticky that says how to find your error/debug file and provide it when submitting a problem:
