Object reference not set to an instance of an object frosty mod manager

[Mucash46]

Hi,

 

I have frosty mod manager 1.0.6.0, handler, merger and string. But when i launch, the following message appears : Object reference not set to an instance of an object frosty mod manager

 

I tested all my mods and the problem is from the Commander Pyre mod. Why that ? Do u have any solutions ?

 

Thanks
