New calendars in cProjects

Hello,

I created a new calendar to use in cProjects. When I try to use this new calendar in a large project, the scheduling activity is timing out. The US calendar for the same project works fine. Is there another step I need to do in order to have my new calendar be used with scheduling without timing out?? Or is it more likely that I need to look at my calendar configuration and fix something?

Thank you,

Wendy
