I can't give you a good answer, but generally when a channel/app unexpectedly closes to the Home Screen there's a bug in the code causing it to crash. It's something the developer has to look into. Try contacting them at:

One more thing, make sure that when you remove it and add it again you perform a "System restart" from Settings->System or Settings->System->Power, as appropriate, after your remove it and before you add it again.
