Installing jquery update causes content to disappear

Hi I installed a few modules today and due to one of them I lost all my content of the standard body field of my nodes.

The modules I installed were:

- jquery update
- strongarm
- bootstrap photo gallery

Could it be that Jquery update caused losing all off my content of the body fields?
Does anyone know how to retrieve my content?

I deinstalled all modules listed here but no result....

Regards,

Mark
