Yeah it's left over code from the full version. Since you can't run sql queries it limits us a bit. btw, if you have ftp access you can set it so you can run sql queries
I'm working on a new package, should have it ready in the next half hour or so, since you can't run queries you're going to need to uninstall the garage and reinstall it with the new package. It will remove the block entries and recreate them, minus the erroneous one.
You wont need to reimport the language or make/model file though, just upload the new files and import the new product.
