Installing campaign confusing/problems

[Ze-Jamz]

Ok,

Im having a problem installing some of these nice Campaigns people are writing..and i still cant work out whats going on, where they need to go etc..

I know you have Steam>game folder>parts>mission etc and thats where they are but they are NOT showing up in game apart from the JG-51 campaign and the enlightened florist campaigns..

Ive lost the campaign installation program that was posted and cant seem to find it again..

Are these campaigns all going in the same place?
Is it a Steam setting thats stopping me from seeing them?
does the install program actually work?

Im a bit lost and also i have a duplicate second install that i use Offline with the sound MOD and ALL the campaigns ARE showing..

Ive looked at both folders and nothing is different in the 'mission' folders or the Parts>mission folders..both installs look the same but my main install doesnt show the campaigns other than what ive already stated..the Modded install shows them all

'Doing me ed in'

any ideas?
