Same problem here, except I'm missing 4,000 points. I know they say that once a day the points are updated on the phone, but mine should have been updated by now (not to mention those 4,000 points are OLD points, not new ones, so they should be on there regardless).
I also have the problem with the error message, and I have plenty of memory as well.
And my stats (rank, report count, forum post count, etc) have been frozen for two weeks. Maybe it's a blackberry problem. I have posted about it several times on these forums with no response from support... I'm kind of disappointed, honestly. I love waze, and it's okay if there's a bug... but it would be nice to know what is wrong and if I can EVER expect my stats to be accurate again.
