the problem is that i had an id of my friend. before loging in windows store with my frndz iD, my id is working fine. but when i loged-in with my friends id it prompt the errror. and then when i tried to login with my own. then the same error appears. !
i think there is an issue with windows store :[ because action center detected an issue at the same time while i loged-in with my firendz iD !
the problem is with my firends id :[
also when i shut my lapi Off and then restart after almost 12 hours. Store is accepting my id smiling
