Re-Installing

I'm thinking of reinstalling my game & I would like to know what do I need to back up or do I need to install each & every patch all over again?
Also I'm in the middle of a season will I have to start all over by doing this?

well iam not 100% sure but i would of thought that if you copy your current render file, save file and whatever else you need then just paste then back in the neccessary files and that should work, but like i said iam not that sure.

Generally your season and roster saves (and indeed anything stored in your My Documents folder) do not get wiped when you reinstall but if you like, you can back them up as well.

Thanks for the info...
