I use a lite version before. It is very smooth and useful so i bought your full version.
(1) But the full version cannot smooth to watch a drama. Sound first and Picture delay. Cannot accept.
(2) I run another document. This is the worst becuase no sound after 1 min playing.
I don't know why having these problem. If you full version is not stable, I suggest you stop to purchase. It make me so disppointed. I hope you can refund to me. I cannot accept your software.
