Texture pack error

[captain50000]

Today I wanted to play in singelplayer and when i started the game it gave me an error.
Can someone help me.

What texture pack are you using? Have you edited any yourself? Are you using the new custom block / texture options?

You are starting in SP and your loal game has no "custom" stuff.
That sounds ok ... simply hit continue.
Message is a bit irritating i guess.

this massage is shown up when you use old settings.cfg
just delete it and load the actual one
