Update Install Failing

[Bison]

I just purchased FG on Steam. When I try to install updates to the program, it reaches the following error:

HandleFile
Unable to save file (modules/DD Basic Rules) to content vault.

I've tried to re-run the installer update several times and reach the same error. I'm not sure what to do to fix this issue so the program will finish updating and I can start accessing the content.

Thanks

Disregard. I had placed the key in the wrong box. It's a little confusing because the wording makes it seem that the full client should use the bottom key box and that the top box is for ultimate client keys.
