Something like that, but if you're going to exec that it'll just not work properly.
(easier way)
Do this instead: schedule(0, 0, yourFuncHere);
function yourFuncHere()
{
MessageBoxOK("BLIVE" , "To open up BLIVE's client from anywhere in the game, press X.");
}
This can get annoying each start up, may want to make some kind of preference
