Having multiple issues and hoping to get some resolution.

1. Steam won't load past lh_remove_prefs.exe
• Renamed the file to lh_remove_prefs.exe.old
• Resolved but is the file needed?
2. Steam won't load past lh_screens_cache.exe
• Renamed file to lh_screens_cache.exe.old
• Game now loads but again, these files must have purpose, them not fulfilling it may lead to my next issue.
3. Game crashes for no apparent reason
• Only occurs when I click to move units and the turn ends in the same instance. Does not always occur
• Crash dump one: https://www.dropbox.com/s/fokfp50ro0ssshu/legendaryheroes_15_crash_2013_5_21T4_33_11C0.mdmp?v=0mcn
• Crash dump two: https://www.dropbox.com/s/us23x0a5rx0wvea/legendaryheroes_15_crash_2013_5_22T0_51_5C0.mdmp?v=0mcn

System Specs:

Thanks for any help or enlightenment in regards to my issues.
