This has never happend before... Trying to connect with grandkids on WFC with Mario Kart wii.  We have played on WFC with other friends in our list including Texas, Colorado, New Mexico, and of course friends here in Alaska.  Never had problems joining with them on several occasions even though we are in Alaska.  Have had disconnects after Joining but never flat out not bieng able to join.  Anyway we have tried all day to join with the grandkids in Indiana.  we dont get an error message just the message "Cannot join at this time try again later" We did enter their license codes like we have done for all the others and then once we showed up on each others lists we tried to create a room and join but got the message above.  We also tried meeting up while the other was playing worldwide and tried regional and vice versa.  Same message every time.  both systems are upadated and are identical in the settings.  Both can play others in regoinal and worldwide.  Just cannot join and play together.  Any ideas on how to fix this? or at least a place to start?  Thanks
