I first posted this on the comments section on the ModDB page for SotP, I was told to post here with the minidump file. Below you can read my original post:

Ok, first off im going to say that I have indeed followed all the instructions and the mod works fine for me. This is a problem my friend is having and he installed the mod following my instructions, and as stated above, the mod is working for me so I do know how to correctly install it, for some odd reason the mod isnt working for my friend.

So, the game has a minidump when my friend clicks Matchmaking. From what he's told me he was able to play singleplayer without a crash. He does have a 64-bit machine with 8 gigs of ram, so ram shouldn't be the problem here.

When the game crashes it says he should use LAA, which he has already applied to the game following my very own instructions (I even used pictures).

He bought the game solely to play SotP and we were really hoping to have some fun together ingame. Any advice is welcome.

I'm sorry about you not being able to work with my friend directly but he isn't exactly a tech-savvy person and I have to walk him through just about everything. The link below links to the minidump file. I would've attached it here but the max file size here is 2048 kB so I uploaded it to Google Drive.

I hope you can help as he and I were really looking forward to playing. Thanks!

I know the exact issue. Your friend recently bought the game, right? Did he ever play vanilla multiplayer? If not, he does not have a SoSE online account with Ironclad Games. Disable the mod in the options to get to the original game, then click on ICO/Multiplayer. Make sure there is an account linked with his game (he will have to make one); then it should work. SotP uses the Ironclad servers to play matchmaking games on, so without an account he won't be able to play online; and thus get the error he was getting.

I had this same exact issue when I was first playing. If there is no account linked in the vanilla game, it will crash and give you that exact error. Try having your friend create an account within the vanilla game, then re-enable the mod and try again.

Good Luck!

I should look into adding that into the troubleshooter. I bet there's an empty field somewhere in the settings to look for.

Sorry about the late response, but I was on vacation and just got back home. My friend says that SotP is working fine now. Thanks for your help!
