I'm having problems accessing internet tv in windows media center. I have tried to run program as admin., i.e., sfc/scannow prompt, cd/d%windir%\ehome>start/waitmcupdate-uf, cdc:\windows\ehome>start/waitmcupdate-u-nogc, neither of these three prompts helped. Have also tried uninstall windows>re-install windows, also no help. No error message appears, posts as successful download but no internet tv tiles appear. Tv guide appears but does not respond. Any and all solutions are greatly appreciated. Thank you in advance.
