ICal cache is corrupted

Question

I'm getting the following errors from iCal:
9/7/12 10:37:13.629 AM iCal: CoreData: error: (11) Fatal error.  The database at /Users/lisamaco/Library/Calendars/Calendar Cache is corrupted.  SQLite error code:11, 'database disk image is malformed'
9/7/12 10:37:13.629 AM iCal: WARNING: CalDAVAccountRefreshQueueableOperation :: refresh :: save failed
9/7/12 10:37:13.630 AM iCal: Error: Error Domain=NSCocoaErrorDomain Code=259 "The file “Calendar Cache” couldn’t be opened because it isn’t in the correct format." {
    NSFilePath = "/Users/lisamaco/Library/Calendars/Calendar Cache";
    NSSQLiteErrorDomain = 11;
    NSUnderlyingException = "Fatal error.  The database at /Users/lisamaco/Library/Calendars/Calendar Cache is corrupted.  SQLite error code:11, 'database disk image is malformed'";
9/7/12 10:37:14.110 AM iCal: Account refresh failed with error: Error Domain=NSCocoaErrorDomain Code=259 "The file “Calendar Cache” couldn’t be opened because it isn’t in the correct format." UserInfo=0x7f8e0fd39c10 {NSSQLiteErrorDomain=11, NSFilePath=/Users/lisamaco/Library/Calendars/Calendar Cache, NSUnderlyingException=Fatal error.  The database at /Users/lisamaco/Library/Calendars/Calendar Cache is corrupted.  SQLite error code:11, 'database disk image is malformed', AccountName=[email protected], CalDAVErrFromRefresh=YES}
Ok, so I get it.  But what do I do about it?  My iCal entries *should* be in the cloud (they are showing up on my iPhone).  How do I clear or delete and recreate the cache?

I am having a similar problem with error message from icalendar: when I try to enter an event on my Mac from an  airline website.
Access to “Bestillingsreferanse:5AG62F, Fra:Bodø  Til:Bergen (WF615)” in “SCHOOL” in account “iCloud” is not permitted.
The server responded:
“403”
to operation CalDAVWriteEntityQueueableOperation.
But on my Mac there is no calendar folder in the library, no calendar cache to be found... ??? How can that be? I see on several forums the same advice: library/calendar/calendar cache. But in my library there is no folder for calendar, and no icalendar item listed in the "caches" folder.
Otherwise I have no trouble synching calendars between my Macs and icloud... just this message everytime I try to open an .ics file from downloads.... but more disconcerting is the lack of a calendar folder in the library! Are these two problems related?
