It might help if you were a bit more specific, e.g., ''I chose Help - Updates, and this happened, then that happened, then an error message that stated 'xxxxxx' was displayed''.
It could also help others help you if you'd describe your system - what kind of hardware, what operating system, etc. One good way to do that is to choose Help - System Info in Photoshop, then copy and paste the info into a post here.
When I click on UPDATES, nothing happens. The drop down menu goes away and you return to the program as if the UPDATE function wasn't selected.
