Very quickly, I think you're in a good position to resume your studies in another program. Your interests changed, which is natural, and in no way should that stop your from being accepted into another program. Also, Graduate admissions aren't that petty...
Do not return to your current program, and apply again in the next cycle. If, perhaps, you're interviewed and asked why you left your program, explain it to them in a succinct, gentle manner. If you really feel that it's going to raise a red flag to the admissions committe, follow La Di Da's advice, which, in my opinion, is both objective and sound.
