Hi all, Hopefully someone can help, Have a timetable built in NOVA T6, everytime I try to export the cycle it says multiple license active: define in SIMS. I have defined a new cycle, but then when I try and export the curriculum and timetable it says that it doesn't lie within a date range, I am now at a loss, and stressed, have spent ages building the TT, now just need to get it into SIMS. Regards Dave
