Kodi Stopped working completely

So I am very new to this Android box, I just received it and every app I go on is either empty or fails to open, and any app I download doesn’t work due to either a 404 error or just says ‘failed to open’. I have viewed the log and none of it makes sense to me but and I can’t seem to find a tutorial on how to get a log from the box to the PC so I can upload the log to this site. If someone could tell me how to fix this or how to get the log on here it would be kindly appreciated, cheers.
