its not that kind of error message, this is a cpp error, with the cfgweapons\ stuff, theres definately something wrong with the cpp or im missing an addon youve made to go on the soldiers, i know youve made an rk76 did you try to put it on some of the soldiers and not include it in the zip?
[edit: found the error, its in the UCE_Finn.pbo]
