Aperture 3.3 > Problems with Previews after Upgrade Library

Hello everybody, I was having the same problems as everyone else in the Upgrade Library process in Aperture 3.3.

I did the checklist bellow and now I am having a strange Preview problem. See second item list bellow.

I tried to post the steps the problem and solution came to me hoping that it will help others.

1. First I downloaded the Aperture upgrade (3.3) and try to open and upgrade my library that was in an FireWire external HD;
2. It got stuck on one of the steps (I can't remember which one);
3. Force quit, I tried again and no success;
4. I copied the library to my internal HD and tried again;
5. It open in Aperture 3.3 but I was stuck with the "0" photos problems in many projects (mostly the ones form 2011 until now)
6. Try repair, rebuild and restore and nothing;
7. I got a backup of my library from my Time Machine;
8. Copied the library back to another location in my internal HD;
9. Downloaded a Aperture 3.1 trial installer from a torrent;
10. I renamed Aperture (3.3) to ApertureXXX and installed Aperture 3.1 trial;
11. Open My backed up library and repair permission in Aperture 3.1;
12. Close Aperture 3,1 and open Aperture 3.3;
13. It asked me to upgrade my library;
14. I cross my fingers and all went smooth;

The problems seems to be when you upgrade directly in Aperture 3.3 and something goes wrong (I never though Apple would le something like this happen), then you have to open a backup in Aperture 3.1 and do it again.

Or the problem may be in doing the upgrade in a library that is in an external HD, something that does not make any sense why it would not work.

Hope this Helps you all get your library and work back in order.

I am Happy again!!! : )

And remember backup is the only way to go.

PREVIEW PROBLEMS

Ok after I was able to upgrade my library and get all my photos back, I have some weird preview problems. Using the split view I have the correct previews but using the Browser view I get wrong previews (check images bellow)

Correct Previews in Split Mode

Wrong Previews in Split Mode Grid Previews

Wrong Previews in Browser mode

This really seems to be a preview bug as it shows correct in Split View Mode.

Any one have this issue? What Else can I do?
