If you want a quick work-around do not try exporting from Premiere, just save and exit the project after you are through editing. Open AME and under File, select Add Premiere Pro Sequence, browse for your project file and click on it once--have patience Adobe's feedback here is lousy--your sequence will finally appear in the Sequence window, click on it and then click on OK. Select your Format,.Preset and Output location. If you want to tweak your settings just click on the Settings button. Then hit Start Queue.
Do you have the project on an external removable drive?
I've been experiencing the same errors,
this solution seemed promising except when I selected the Project in the Add Premier Pro Sequence window (and waited like 5 minutes) it stated there was an Error with Adobe DynamicLink
