Arma 3 Launcher - error - cannot find base class

[Ninjaxdeath]

Hello,

After I installed my mods, step 7, I attempted to load Arma III to ensure it loaded the game and mods correctly, as the install video suggested.

I'm getting an error that states:

"
bin\config.bin/gm_slotMuzzle_556x45mm/compatibleItems/:
Cannot find base class 'compatibleItems'
"

I tried googling, but it wasn't very helpful.
Can anyone offer some advice or instruction?

Hello RCT Cuthbert,

This looks like it might be a mod error - it is possible that one of the files was corrupted on download.

Please double check you followed the instructions in the PM you received and consider starting fresh by deleting the files and reinstalling.

If you're still having issues at that point, please send a message up your CoC for assistance.

Regards,

PFC Speirs,

Thanks for the advice.

I uninstalled Arma 3 completely, removed all files from Steam Apps > Common > Arma 3, reinstalled.
Then I downloaded each mod one at a time, then I unpacked them one at a time.

I followed all instructions from the PM to a t.

I'm still getting the same issue, same error.
When I launch Arma 3 without mods, it launches fine with no errors.
