Hi M.!
I am sorry but I don't have any ideas of getting the paint out other than cutting it out.
However, you did say that the stains/paint were in the middle of the room. Why not try the other suggestion and if that doesn't work, put an area rug over the spot. I have seen many rooms be accessorized with an area rug over existing carpet. I have done this for places where I couldn't get wax out of carpet or wanted to conceal and lessen worn areas in a carpet.
Good Luck!
