Man sometimes the simplest things get overlooked!
Thanks southernlady for pointing out that which I didn't spot.
Optimissed: You have to have a high speed Internet service there somewhere if you "have DSL" . That would be through the local telephone company or a third party company and uses the telephone wire and a separate DSL modem (box with green flashing lights) and network card in the computer.
You may be seeing on the AOL 9.0 Welcome Screen (Optimized for Broadband)
Your user name here at TSG suggests that...and since it is not the first of April

I am going to assume you are not pulling somebody's leg here...and have just confused the newer software title with having DSL?
You can keep and use your old dialup account when you switch to DSL broadband.....but do have to pay a monthly fee to do that. (Bring your own Access it is called). AOL dialup (not highspeed or DSL)...when I last had it was $24.95 per month. (called 56k or just dialup service).
You might be paying for both. Lower DSL service through our local telephone company is around $34 a month, and you would pay AOL the $14.95 on top of that to" BYOA" so you can still use your AOL account, email, etc...
TV cable companies have cable broadband (no telephone wire is used) Same type of external modem, TV cable and network card. You'd have to live within a TV cable company's boundary to have that. Satellite is another type of highspeed service, but you have an outside dish receiver to get the signal. You pay someone like Dish Network for that service usually as part of the regular satellite TV montly fee.
If you have an AOL account and can sign into it...you had to have started with dialup connection. Maybe you could check your credit card statement for another ISP? Or, call the free telephone number and speak to an AOL billing rep
