Critical Error Recieving Profile Data

I had downloaded a mod that adds the Benelli M4 Super 90 (M1014) to the game. I couldnt find the the extra attachments, such as the railed handguard, that SamSwat included with the mod. In the support forum, I had told of my issue and had gotten a lackluster response by SamSwat. Then a Russian fellow replies sometime later, explaining that he set up a Flea Barter to resolve the same issue i had gone through. When I tried to set one up myself the game gave me this error

When i restarted SPT it would attempt to load profile then give me this error and close the game automatically

I cannot access the game any longer, as it boots me out everytime i try to load the profile. I have not tried creating a new one because id like to attempt to resolve this issue before doing so.

Somebody please respond, im on the verge of tears here, i just need a hint or some know-how

Edit: All somebody had to tell me was to change {null} to 1. Thanks for nothing guys.
