Problems with downloading Mods to arma 3

[Final_Joint]

I can load all my mods and maps fine but when i start arma 3 i get only one problem which is an error message that reads- addon 'AIA_Core' requires addon 'A3_Air_F_Gamma_UAV_01' Any suggestions?

Verify your ArmA 3 game directory.

A3_Air_F_Gamma_UAF_01 is apart of Vanilla A3 and therefore it sounds like you are missing data from your game.

Right click ArmA 3 in steam, properties, local files and click verify integrity of game cache.

Be warned that it will remove anything from that directory if it doesn't think it should be in there.

It also means you are not using the correct base version of Arma 3.  This happens when you are not on the same unit version.  Which should now be 1.60.

Thank you for the assistance that seemed to do the trick and apologies for any inconvenience.

Disregard last message i am still getting same error message after Verifying Arma 3 and making sure 1.60 is up to date.

When was the last time you updated the mods used on the  server. I think the reason i cant load onto the server is because i have out dated mods.

We just updated the mods this week.  Check your PM's I'll send you links to the current ones.
