NWN toolset crashing when after I test module

After I test the module and return to the toolset I get a Access Violation error and I have to close the toolset then reopen. I noticed my version of the game is build 8193.5 still. I went to steam but it has not auto-updated to the hotfix build 8193.7

Do I have to manually download something?

If you open the Steam client, then select the Library tab, you should see the development build.

Caveat - I’m using a Steam key provided by Beamdog, rather than a direct Steam purchase, so your experience might vary. I haven’t actually installed the development build on Steam as I already have it from Beamdog (which only works if you purchased direct from them).
