OK, let's go back a step shall we?
Maybe you better tell us what software you are using and what versions you have and what steps you take to get the error you are receiving (or missing option as appropriate).
i.e. what are you trying to export from and what version of AE are you going to import or have I got it round the wrong way.
I'm not familiar with the s/w at all but others here might be so if you let them know your versions and what you are trying to do (step by step please) they might be able to help.
I'm presuming you have gone through the FAQ at

Alternatively, you might be better off contacting their support people.
