I have an Andor camera with an Apogee FW50-7S filter wheel. Everything was working fine with MaximDL 6.20. I updated to the latest version last night and now every time I go to setup filter and connect the camera it gives me an error saying the filter wheel could not initialize and it refuses to connect to the camera. I tried updating the drivers for the filter wheel and camera and USB ports and windows insists all drivers are up to date. I have no idea what to do but I need this resolved ASAP. Any help would be appreciated.
