CTD because Missing Weapon Upgrade? Thread - MISERY mod for S.T.A.L.K.E.R.: Call of Pripyat

Hello, I'm having issues with a crash, as I examine the Xray report, apparently some file is missing.

FATAL ERROR

[error]Expression : fatal error
[error]Function : inventory::upgrade::Group::can_install
[error]File : D:\prog_repository\sources\trunk\xrGame\inventory_upgrade_group.cpp
[error]Line : 101
[error]Description : <no expression>
[error]Arguments : Loading item: Upgrade <up_thirdc_desert_eagle_custom> of inventory item [wpn_desert_eagle_custom] (id = 7369) can`t be installed! Error = result_e_parents

This is the fatal error I keep encountering, I can't enter skadovsk because it crashes the second the game loads up the technician. I do not understand what file it is requesting specifically, so if anyone can please help point out what file I need to fix this issue so I can continue playing MISERY, I'd appreciate any help I can get.

Update*

I found the loading item that can't be installed, however, I don't see the issue with the line of code that is causing me to have CTD.

I found the file in this address path. C:\Program Files (x86)\Steam\steamapps\common\Stalker Call of Pripyat\gamedata\configs\weapons

Picture of the Code; Gyazo.com

I am playing with The Armed Zone mod, is it possible that this error could be attributed to them?

You haven't installed it correctly or are missing a patch. Search the TAZ thread and I'm sure you will find what you need.

I found the fix in the TAZ forums, thanks for the help.

My pleasure. To get the quickest solutions, if you have any add-ons besides the Misery mod try their thread first. I watch all the threads, so your answer may still initially be from me. That also helps keep solutions to new problems in the best thread for people to first look.
