Need your help with FiddlerCore error

Dear Fiddler Development Team,

You colleagues from Smart-Soft here. We use FiddlerCore as part of out software - Traffic Inspector.

We have encountered an error with Fiddler software. It goes as follows:

Uncaught Exception in Session #7095 - Fiddler has encountered an unexpected problem.

So, what may be the problem? 

Thanks in advance

Hello,

Sorry about the late reply.

Is this a problem with Fiddler or with FIddlerCore?

Hello,

It is FiddlerCore - a library used in our software.

So what are we gonna do about it? Are you going to help us in any way?

Hello,

Are you actually using  Fiddler v3.0.2.916 ? When did you get this one? Is updating to latest version an option?

The latest version includes .pdb files. Since what you are using is really old I am not quite sure it has .pdbs. Either case we need the .pdb file in the same folder where FiddlerCore.dll is at the time when the exception happens. That will give us more info.
