Inwprld is on the default list. Your "Grids.txt" file must have got replaced by an old version somehow. If you delete Grids.txt from your Roaming folder (yo ucan access it fro mthe About menu option under the Help menu) and re-start METAbolt the Grids.txt file will be recrated with the defaults upon login.
Alternatively you can enter it manually by selecting "Others..." from Grid dropdown box on the login screen, and then by clicking on the paper and pencil icon to the right of it. Simply eneter the blow into the notecard that will appear and then save the notecard:

I can't see a problem with the inventory in Inworldz. It worked fine when I logged in! Are you able to give more information as to what exactly happens when you log in? Is it blank? Do you get an error? Are there any etnries in the Debug Logs under the Logs menu?
Thx
