When all features were supported I was reffering to the free version of AM, so technically that's why VBScript isn't supported.
Edit:
These are all the features supported that AMTransformer does not have:
-Access to menus
-working inventory
-Vista Tested & (most likely) Win7 Support
Also, if you don't wish to have the AM Icon for your game, you may remove/replace it with the XN Resource Editor (for advanced users), as well as add version information / copyright to your game.
