The A330 disappeared from P3D, so I've had to edit the add-on.xml to point at the correct location and it's now as below.

When I load the A330 I get the following two errors, and the simulator is totally unresponsive/sluggish.

Hello BenG,

The second error pop-up indicates “add-ons.cfg” as the source of the error, not “add-on.xml.” I don't have P3D installed, so I don't know the location of the .cfg file. However, I suspect it is within the aircraft folder. 
Perhaps the two errors are related.

But I could also be completely wrong.

How about a fresh installation of the A330?
