After upgrading LanSweeper to version 126.96.36.199 the knowledgebase no longer works. All the categories I created are there with the number of articles are shown on the left but if I select a category it says there are no articles yet. I also get the following error if I try create a new article. "Object reference not set to an instance of an object". I also get the following error if I select the helpdesk tab -"An error occurred while getting the data from the database"
