Extension talk:Makesysop

This simply doesn't work. I get this error:

Fatal error: main: Failed opening required 'D:\inetpub\webs\lordphoboscom\public\wikicomio\extensions\Makesysop/../ExtensionFunctions.php' (include_path='D:\inetpub\webs\lordphoboscom\public\wikicomio;D:\inetpub\webs\lordphoboscom\public\wikicomio/includes;D:\inetpub\webs\lordphoboscom\public\wikicomio/languages') in D:\inetpub\webs\lordphoboscom\public\wikicomio\extensions\Makesysop\SpecialMakesysop.php on line 49

How can I fix that?

SpecialMakesysop.php on line 49
I get a similar error ...
