Football Manager 2014 Low on memory.

I tried to load a save this morning and during the loading process, an error popped up with this:



I press OK and this occurs:



And FM freezes completely, needing me to end the process.

It only happens for this one save, my others work fine. There is less leagues loaded in the save that causes the error. I have tried deleting all graphics, resetting preferences and cleaning up my disk to create more space and the error still occurs.

Thanks for any help.
