Morning Ana. Some plugins do make our units have a nervous breakdown but the hard reset usually will bring it back to life without too much trouble. One of my weather programs used to make my screen blink real fast, a soft reset took care of that. After a few times of watching it I dumped the program and things seem to be back to normal. Good luck.
By the way, I used to be stationed in the UK at Milldenhall back in the 70's. Loved it out there. Would like to go back to visit one of these days.
