Failing to load mods

I have just installed all the DLC for GSB and whenever I attempt to load a battle in campagin or normal mode the game will crash with an error of failing to find a mod which one switchs. Please help?

“Failed to find exp_sparkburst:…\src\GUI_Explosion.cpp102” - latest error message

If i find a situation where GSB is throwing an error due to a mod - but you can not determine which one, I run through the following process.

Step 1: Back to first principles.
Open \Gratuitous Space Battles\data\installs
In there you will find all the install files for Campaign / DLC & Mods.
Rename every mod.txt file to - for example:
unit.txt ->
Classic DNs.txt -> Classic

Step 2: Move or delete your designs.
Open \My Documents\My Games\GratuitousSpaceBattles\ships
In there you will find all your designs for the various factions.
Either delete them or move them somewhere else till you solve the problem.

Step 3: Run GSB.
In theory, GSB will not open any mods and there will be no ship designs from mods to trip it up.
From there you reintroduce each mod (by renaming .off to .txt) one at a time and find out which one is causing the error.

Once you have found the mod its then a case of trying to find out what is causing the problem
(my guess is a hull file)
