FedEx shipping module issue

[MyNetworkSolution]

I installed FedEx module but it broke during Checkout process (a blank page displayed). This is the error I've found in the log file. I hope someone can please help me fix this missing file. Thanks in advance.

It looks like you may not have installed this addon correctly ...

You may wish to go through all the steps to install it and see if you missed a file or files(s) on the install ...
