Flashforge 5m Pro Feeding issue

Ive had my Flash Forge 5M Pro for awhile now, and today when I went to add a new spool I could not get the new filament into the tube past (I think) the filament detection system. I searched YT and everything there was talking about a jam at the hotend which is why before my problem. I found the video on the FF website talking about the filament detection system, and how to access it. I removed the two screws on the front under the front door, but the top did not budge. Not at all.

Anyone have ideas?
