Content Manager launch error

[andremlanca]

Hello everyone. I'm new to the forum and i could really use some help. I'm sorry in advance if this is not the place to post this.

Whenever I add any content to content manager or, if it updates to a new version, once i click go! I get the following error:

"Object reference not set to an instance of an object."

Checking the Mainlog.log i found some errors:
