If I uninstall then re install BF4 Will I lose my multiplayer progress, or do I keep it

I don't really care about the campaign but I really don't want to lose my progress, some person at EA on the forums told me to uninstall then re install bf4, and he didn't say anything about losing progress, please tell me if I will lose it or not, I AM SCARED

Thanks! I was really getting worried, Do you know about the solution to the Error of the invalid license agreement, is there a solution, or is the solution just uninstalling the game and re installing?
