Delete multiple calendar events that appeared after synchronizing?

[Dan W]

After synchronizing my desktop and PDA, my recurring calendar events
multiplied, now showing many duplicates of the same event on the same day.
When I try to open one of the events I get the message "Can't open this
item, object not valid". When I try deleting the events I get another error
message saying it may not have deleted correctly and the source for the event
may not be updated, event not valid.

Dan, have the same problem here, can't find a solution. Have you managed to find one?
