Daburban - You will still make beer and it will most likely be good given time. Lager yeast will not be the same at higher temps, and vice versa for ales at lower temps.
I do not mess with switching up yeast because both the yeast strains and the brewing tradition have been around a lot longer than me. But, the best brews I have made have been due to major mistakes, and I don't think I could reproduce them if I tried.
In any case, Welcome to the forum, and brew some good beer.
