Hi Winston,

Any v2.x.x version of the framework will be fine (at time of writing, the latest version is v2.2.5).

There are two routes to getting this version:

1. If you wanted to keep your existing install, you can try running the upgrade script (i.e. node upgrade), entering n when asked if you want to update automatically, and entering tags/v2.2.5 when asked for the framework version (you can leave the authoring tool version blank). You can get a bit more information on upgrading here.
2. You can also run the install script again (i.e. node install), and enter tags/v2.2.5 as the framework version.

Good luck, and let me know how you get on!
