HiI have a Celestron Nexstar 4SE+ that I bought a few years ago.It's been in storage for a few months. This morning I tried to set it up again with a view to enjoying the sky tonight, and to my disappointment the motor is not working....When I first powered on, it showed this error message:bootloader invalid package 0099I powered on and off and now it loads up fine and goes into the alignment mode on start up.However the motors are not responsive at all when I use the arrows to try to do the alignment.I'm wondering if there is anything I can try to do to resolve this and/or if it's likely to the "controller card" that is the issue, broken motors or something else.If you have ideas of what I can try that would be great. Alternatively if you have could suggest a path to getting this fixed that would be much appreciated.Thanks so muchWith Kind Regards

I did look at this guidance for updating / fixing the firmware. However it looks like I'd need a cable + custom serial/usb connector that I don't have & wondering if it's worth investing in given that the error message is no longer coming up when I boot up the telescope?
