You always seem to get in trouble mmmm? (Wonder who u learned it from). anyway it seems to be a smeltery problem, just dont try to do what Eva u did again mmmm?.
it happened 5 times then i deleted the instance and did it again and it worked fine until this morning where i got this at log in
The second error just meant that that minecraft session servers were down, nothing to do with the server. The first error, if after re-installing it no longer happened, then it should be fixed as the two errors are unrelated.
