SemanticMaps 3.0c error

Wanted to give SMW 1.9 a whirl, but got hung up on this error:

Fatal error: Call to a member function setInputTypeHook() on a non-object in C:\inetpub\wikiocity.com\dev\extensions\SemanticMaps\includes\forminputs\SM_FormInputs.php on line 101

I have all of the extension dependencies, but I'm still on Mediawiki 1.20. Is 1.21 absolutely necessary, or is something else causing the error?

Thanks!

This looks like you are loading Semantic Forms after Semantic Maps. It needs to be the other way around.
