After update to 2.0.22 my products in backend dissapeared!

[bwise]

Yesterday I updated VM to the latest version 2.0.22. The server runs PHP 5.3.23 An I use Joomla 2.5.11
But after I used VM for an hour or so suddenly I didn't see my products (and categorie) in backend anymore. Als I was not able to make any new products. If I did, VM told that he succesfully saved my product, but there were none in the list.
After asking this question on a Dutch forum, I discovered not to be the only one, but no one had a solution.

I dit re install VM, but my products are still gone, but visible at the front-end. I can even make an order. After re-install I was able to make a new product, but it did not appear at the front-end.
Do you have any suggestion?

Ok, i figured out (via the Dutch forum) that this answer works for my problem:

This sollution does not work for me.
Since the updates I have been missing the categories and the products in de backend.
They are still in the database and I can order them in the frontend of the site.
Al the rest of VM like the list specials fields, tex an discouts rules I can see.

It looks like VM can not connect with some tabeles in the database.
Help.. please... My customer is not pleased with this..
Thx
