Aol Upgrades And Ndiswan - Help!!!

[CYAAA]

I HAVE BEEN TRYING TO UPGRADE TO AOL 9.0 FOR MONTHS..I GET THE SAME ERROR. "YOUR SYSTEM ONLY ALLOWS 8 INSTANCE(S) OF NDISWAN". I HAVE TRIED REMOVING ALL VERSIONS OF AOL AND REINSTALLING 9.0,WITH THE SAME PROBLEM.NOW AFTER GIVING UP ON 9.0,I TRIED TO REINSTALL 8.0(WHICH I HAVE SUCCESSFULLY HAD ON THIS MACHINE BEFORE),I CANNOT INSTALL THAT EITHER! THE ONLY VERSIONS MY COMPUTER WILL ACCEPT IS 7.0 OR EARLIER(WHILE GIVING ME THE SAME MESSAGE)..AOL HELP IS NO HELP..I AM RUNNING WIN98SE. PLEASE HELP! THANKS! BARB
