WOTLK - Binding Error

When attempting to use the "Keybind" feature in Macro Toolkit, I get this lua error:

```lua
1x MacroToolkit/modules/bindingframe.lua:90: attempt to index field 'text' (a nil value)
[string "@MacroToolkit/modules/bindingframe.lua"]:90: in function `CreateBindingFrame'
[string "@MacroToolkit/modules/mainframe.lua"]:1031: in function <MacroToolkit/modules/mainframe.lua:1031>
```
