wxstart.exe "Advanced Section" error

[Lord Speed]

At this application "wxstart.exe" there is a menu called "Settings" and if you'd go to "Advanced" and select or click a category it will say it is downloading something, but then an error will pop up that suddenly closes so you cannot read it.
The error.txt it made is this :

OpenKore version what-will-become-2.1
Network state = 4
Network handler = Network::DirectConnection
SVN revision: 7916
No loaded plugins.

Error message:
Can't call method "getData" without a package or object reference at src/Interface/Wx/ConfigEditor.pm line 217.

Stack trace:

Died at this line:
my $len = 0;
* $size->getData($len);
$progress = $len / $size * 100;

I think I can really use that Advanced section, so if anyone is willing to help please reply
