Very sorry for the delay in getting back to this. The changes were a little more than we were expecting, so instead of just making those changes on your site, we rolled them into the 1.0.1 release that we were planning this week. I installed that on your site, enabled the JLinked System plugin, and voila! No errors. There were a few other changes/updates/fixes in the 1.0.1 release, which we'll have a changelog up for shortly.
In general though, hopefully you're good to go now! Of course, please test, and should you run into any other issues though, just let us know.
Thanks,
Alex
