Edited games won't load!

FM2012 works fine when 'un-edited', but only loads about a quarter of the way up the loading bar when I try to start an edited game. I paid for my copy of FM, I have re-installed both the game and the editor numerous times (to no avail, this did work once but i'm pretty sure it was a fluke!), I have tried edited games with and without added nation rules. This problem has only occured since about March time, and was fine before-hand. I have been working on a massive project of nearly 30'000 changes (yes, i'm single), and this won't load up, but I've tried loading a new game with only one change, and this doesn't work either. Any ideas or solutions would be greatly appreciated, thanks in advance for any assistance.

hmm...this is not a normal bug...have you tried different PC? i mean have FM install on a different PC and see if it works?

30,000 changes and it doesnt load...lol

but seriously though i think this is something for the SI gurus to answer, i mean ur having trouble with every single different edited games right? so its something wrong with something.

Thanks for replying, I haven't tried it on a different PC, but will if I get the chance!

It's pretty shit really doing that many and it not working, i changed every recognisable feature in the game!

And yeah I'm having trouble with any edited game i try to start, but unedited games start fine.
Don't know who these 'SI gurus' are though as I'm pretty new to the website.

ah by SI gurus i meant Sports Interactive the game makers, on their forums they usually take in such bugs and hopefully can give a solution.

I've taken it up with them, and found a thread devoted to the same exact problem and am now waiting to hear back.
