My ical does not open. Please help!

Once I click on it, it will bounce and try to open.

It keeps bouncing but never closes so I always have to force quit it.

It then sends an error report. Is there anyway I can fix it, or reset it?

It has been doing this a month after I bought the laptop.

I think it might of started when I synced my iPhone to it.

Everything is up to date and I don't know what else to do!

Please help!
