My saved game won't load now. It says

"DatalO operation system Error: CNSL"

What does this mean and how can I fix this? The only thing that i've done is install Patch 1.29.

Is that the reason, because the game i had before didn't have any patches on it. I think I answered my question but I want to make sure, cause I'm really far into this and in the middle of a war with Egypt, and want to see what happens:D

Any way could someone help?
