Nokia :: Synchronizing With Online Ovi.com

I'm probably the author of my own misfortune here, but I loaded a GPX file with about 4000 waypoints onto my 5230 a few days ago. I got fed up after a while as it made ovimaps run like a complete dog, so I used the "location" app to select all and delete. However, it seems in the meanwhile that it had synchronized all of the landmarks to my ovi.com account. After I did this I noticed I was getting "Download error" every time I opened ovimaps, and I realized that it must be having some problems with synchronizing the phone with ovi.com (its set to do this on startup and closedown).

I viewed the maps there today and could see them, and then spent about 30 minutes deleting each of them manually. Online there are now no landmarks, and there are none on my phone either. However, I cannot now seem to sync ovi.com with my phone (using the menu option under "favorites" in ovimaps 3.04 on the phone).Message I get is "Synchronization incomplete” Is there any way to re-initialize the synchronization? I've tried removing the account from the phone but that didn't seem to work.
