OK quick update.
I have removed all my WA extensions this evening and reinstalled them, with SA2.04 being the last on the list.
I've had to replace to manually put WA ColumnTypes.js in the right directory but when I click on OK in the GUI it does nothing. I seem to remember this being the case when SA 2.04 was first released a while back and its probably another file missing from the installation.
Can we get the install fixed so that it installs the actual files required to use the extension without logging a support call?
