Users will need to reschedule exhibitions with the 3.0 update. 3.0 does not allow scheduling of exhibitions until it rolls. So, there is only the 1 night to get exhibition #1 scheduled. Check that at 6 pm EST before doing anything else.
Also, it appears that the new coach signup period has been skipped. That's a good choice as it will speed things along. Like I mentioned before, don't shoot your wad when scouting starts up. Consider registering for a public camp...at least take a look through...maybe use the scouting service for your state at your division, but be patient. There will be plenty of time.
