When I apply the auto scroll effect to my text list of credits it doesn't scroll the entire list. So I tried doing it with the Premiere Pro CS3 title scroll and it worked. I tried to copy and paste into AE and I can copy the text fine, but it still won't scroll. And if I import the PPro project, the PPro scroll doesn't work. What am I doing wrong?
Well, there's a limit on the number of characters a text layer can render plus text animators also have a limited range that may not suffice to accomodate all letters. You need to split up into multiple layers if the credit is really that long. The Premiere effect certainly is not supported in AE as it presents a special mode of the title tool, so no wonder it doesn't come in.
