Nobody can tell you anything without proper system info or other technical details such as system audio settings and preferences.
ok then, what should i tell you about my sistem?
processor? ram? what?
sorry if i was rude )=
I'm not new to AE, i have used it for the last three years, and he was running normaly, then two weaks ago, he started to bug out;
and now, i don't know what to do.
I'm confused. First you say that you just downloaded AE, then you say you've been using it for three years and it was running normally.
And you still haven't provided the requested information.
