New PC, SWBF2 Mouse Malfunction

Just in case any one else has had this, I just got a new PC and wanted to see Battlefront2 on it, and the mouse has had issues from the moment I first loaded the game. First time loading, no mouse cursor  visible. Second time and thereafter it appeared. But once in game I could only turn left or right a maximum of 90 degrees if that. I'd have to upload a video to show how wack it was. The game's just bugging out with my Deathadder Elite and Synapse 4 software from Razer. I've never had this problem before.
