Alex,
The most common issue with schedules not showing up is the days schedules are set for, so make sure of that. If you're getting error messages please post them here. If you don't get errors and you'll see schedules listed up partially then I think the issue goes back to days of week. If you have uploaded a .csv file with your schedules, there might be some fault data inserted into DB. I suggest you re insert schedules table. The last think I would suggest to you is to reinstall phpVMS.
