Extentions in OO V3 Beta 2

Hi

I installed a number of extensions in OO V3 Beta 1. They worked fine until I upgraded to Beta 2.

Now whenever I open OO V3 I get an error message for each installed extension. I tried to disable them to test if I would still get the error message. However the extention manager in Beta 2 seems to be unaware of any additional extensions.

any advice?
