You're very generous with LA. The few lines it's built recently (eg Exhibition Line) are so slow that no one in their right mind would take it unless they have absolutely no better option. In Paris, public transport is always the first option.
Actually, about half of RER Bs are express lines which go straight from CDG to Gare du Nord without any stop. They include a large luggage storage area at floor level, in the middle of the car. When you are at the CDG station, check if your train is going to be an express train or if it will stop at all the local stations before you jump in!
Did you try to get Nitro? Their support is faster for paying users. You could create an alt and try to get Nitro just to get the problem fixed (and if you have a server that you really care about, it's a worthy investment).
