You have to export with a codec that supports an alpha channel, or you could just send the comp to Premiere. If you have a lot of captions you could use Live Text where you can make the name changes directly in Premiere but using an AFX template.
Render as an MOV with the PNG codec and make sure your output module settings are set to be RGB+Alpha
Ok! That worked (RGB+Alpha) thanks! I've never made any changes to the output so this was good to go there and see all my options.
As far as importing the comp, the AE file I purchased uses the same comp to change the names so if I import the comp and change the name in AE it will make all the comps in PR the same. And I'm not that versed in AE to figure out how to do that. But hey, if you wanna teach me I'm all for that!
Thanks again! The RGB+Alpha worked, thanks.
Either save a new file for each new name in AE or render your file from AE and just import the resulting MOV.
