The formatting changed substantially across those updates, and so the mod itself, even though the version number has never changed (on purpose, I've always used date-stamps to denote a newer release).
If you're having problems with a save that's been in 2.600 all along, and only ever used Ewiger Krieg in its native form, then I'm not exactly sure what's the problem. The trainer only alters what's in RAM, so I highly doubt a problem there unless it somehow allowed the game to save a corrupt datafile which could not be recovered by the game at a later point, thus the game effectively disappears. The mod itself could potentially work in tandem with this potential problem, like building a bunch of pershings where you shouldn't have any, and you far exceed the population cap or something... However, even in that case, the game -should- allow for it, save it, and when you reload without the trainer you'll just be WAY into the negative population available because of all the tanks.
If you're trying to load a game from before you started playing with Ewiger Krieg, or games using another mod, or a few other situations I can think of, then save files in those other situations won't be recognized as Ewiger Krieg saves, and vice versa.
All this time I thought it a conflict between the trainer here and your mod. Never tried it solo, what do you think ? It doesn't make sence to me either, they always worked in the past. Now I have a campaign game going with your mod, and they work fine, restarted allies and am playing in Montebourg, it is just skirmish.
Edit: OK, now we are getting somewhere. It is only some maps. Mostly those done by the community, the base maps of Relic's load. Why? I seldom play those maps now as they have been done.

You see, "community maps" are themselves mods, and intermingling mods can work, but it can also have potential problems as well...
Unfortunately, being that the actual cause could be as a result of innumerable things within that map I can think off off the top of my head, and assuredly numerous others I can't immediately recall, I am remiss to do much in such a situation because I can't compensate for what another modder has done within their mod, just as anyone couldn't ask of me to bend my mod around their own.
I'd hazard a guess though that something within those maps is using something that's been addressed in Ewiger Krieg, and the two conflict in one way or another. My first instinct is to address multiple access conflicts, as two different values for one entry is not acceptable to the computer/save.
Well, I have no official ties to any other mod or its creator at this time. Not having meddled with the Blitzkrieg mod I am not sure if there are any conflicts, but that mod altered any of the units in the game then the potential is quite high that somewhere in our mods we altered the same unit in different ways. As a result, Blitzkrieg would be trying to make the unit do "such and such", and Ewiger Krieg would be trying to make it do "this and that", which would likely cause the mods to not function together.
You are welcome to experiment, but I simply don't know what specific compatibility issues may arise from combining Ewiger Krieg with other mods.
