How to stop a process in Kodi

So sometimes, I press links in Live TV addons and then I get setback into infinite loading since I don't know, the stream doesn't work and Kodi is falsely believed that more loading will get it going? (EG: I opened UK Turks and tried TSN 1 and now I am stuck in infinite load)

I am a noob and I have no idea on how to get out of this infinite load without closing Kodi completely. Is there no other way? Thanks

EDIT: Also, when viewing Acestream links and then pressing stop, force closes Kodi 16. Anyone know the fix? Again, I was viewing TSN Acestream....
