Maybe just wait? It's likely that importer wasn't updated yet. If there's author of it given in the addon's code or interface, try contacting him/her and report it as a bug to get it updated faster (one time addon I used wasn't updated for a month, turned out the author assumed it would work on the new version due to little to no API changes, until I've made it aware to him that the addon, in fact, didn't work on the new version).
