I have set several dates in my calendar, but today I've had one alarm that has been going off EVERY HOUR since 7:50am. Apparently it started when I got a text message at the exact same time the alarm was supposed to go off. When I checked the alarm, it didn't give me the option to erase it, and when I go to the calendar, it's not there... but it keeps going off every hour, and I can't get rid of it.

The last time this happened, the only way I could get rid of it was by deleting EVERY item in my calendar. I lost VERY important dates, and I really don't want to have to do this again. Is there any other way to fix this?

Thanks.
