I just downloaded Minecraft PE again yesterday, and i when i signed to Xbox live account, it just crashes. i tried several times and it keeps crashing. i've tried uninstall it and reinstall it. it did crash again but on the 2nd attempt, it didn't. it is good, but if you have to do this everytime you wanted to play Minecraft, you'll get annoyed, don't you? I've also tried different Xbox live account, and it also crashes. I thought this only happened to my main account, but no. Also, when i tried to change my skin to the custom one, again, it crashes.
