After a new instalation of Win XP I downloaded and run Flash player 10 I also had Macromedia Flash shockwave 11 installed in my system. Still many web pages tell me that there is no Flash plugin in my system and they ask me to go get macromedia flash plugin. Is flash plugin somethimg other than Flash player10? Help.
