OpenRA

It's just stopped launching. I've tried it on two computers, tried completely reinstalling it and tried running it in combatibilty mode (Friend's still got it running on XP)

Anyone got an idea of why?

Please post the exception.log that the game creates in Documents\OpenRA\Logs

System.InvalidOperationException: Sequence contains no elements
at System.Linq.Enumerable.Aggregate[TSource](IEnumerable`1 source, Func`3 func)
at OpenRA.FileFormats.Manifest..ctor(String[] mods)
at OpenRA.ModData..ctor(String[] mods)
at OpenRA.Game.InitializeWithMods(String[] mods)
at OpenRA.Game.Initialize(Arguments args)
at OpenRA.Program.Run(String[] args)
at OpenRA.Program.Main(String[] args)

EDIT: This is off the second computer as I don't have access to the other but neither of the programs have been edited beyond me playing with the balancing of certain units.
(Which was changed and worked fine yesterday and on my friends comp so I don't think they are to blame...)

EDIT 2: the main comp's one looks the same to me but here it is incase I've missed something

anyone?

Looks like a bug to me. There's most likely something in Documents/OpenRA or compatibility files for ProgramFiles/OpenRA which has got screwed up.
