Unable to load 3rd party adobe acrobat Plugin in protected mode.

HI Abambo,
Thanks for the reply. To update this, I was able to load DLL , but I am unable to make any api calls through my plugin. I modified some policies even, but still it is unable to make api calls, where as If I disable protected mode, it works fine. 

 Running them , I just receive an error stating : 
Code:  await PostAsync<T>(url, body);

An error occurred while sending the request.
Inner Exception : The underlying connection was closed: An unexpected error occurred on a receive. 

I found that adobe is able to make its own internet calls smoothly, Like check for upgrades and all. Is there any way where I can modify Adobe, so that it loads my sites. I tried adding in Trusted Manager and changed allow pdf files to access websites. 

Thanks in Advance.
