ESP8266 internet connected switch mqtt issue

when i try to compile the code i get the same error below every time. all i can see is about the library and thought maybe some of mine from other projects might be messed up so i've even uninstalled the main arduino program removed the prog(86)/arduino folder and the sketches. then re installed from scratch.

but again i get the same error. only thing i noticed was my previous library list was still there if i went to manae library in the application, even thou i had wiped the folder could that be an issue of a remaining library but if so where?!?!
or is there something that i missing!!
