AH Result Problems + Auctioneer problems

First of all thanks for investing your time in this post and sorry about my english since its not my main language.

I'm having problems everytime I try to search for items in the AH (without addons) and also the same problem when using auctioneer where I can only see like half of the items I should find.

While using Auctioneer my game crashes sometimes getting perma-frozen with this error message:

Thanks in advance.

PD: I've seen like a hotfix (and I think is related with this kind of errors) but I also saw that the hotfix is useless now since the server was updated.

Tell me if you have found a solution please.

No change , I tried and it still instant freze. No crash because I'm not waiting it out maybe . Did a full ah scan after i put the ah addon and today freeze.
