Hi,
Thanks for using the Events Calendar.
Here on the pre-sales forum, I’m afraid we do not provide technical support. I would ask that you take any technical support questions across to our wordpress.org forum – our staff scan it periodically and other community members may also be able to help out.
The Events Calendar
If you have purchased a plugin from us, please login and post in the premium forums for that plugin and we can help you out there:

Having said that there is no limit so something else is happening. When you post in the iCal Forum can you please include the ics link you are trying to import from and we can help out from there.
Thanks again!
