Details of the issue:

So, whenever I open up my world, I get a message that says "Forge Mod Loader has detected that level.dat is being used." It gives me an option to continue but tells me that if I do I can damage my world beyond repair and lose my progress.

I click yes, nothing happens, I click no It brings me back to the menu.

So, what happened?​
