I even tried poco bueno but my roads never change
any help?

If you put all the NMC archvies in the root directory, without the file number suffix and extracted the first one then they should have all gone into the Data Files. So, assuming you did that, then did you toggle Archive Invalidation in FOMM?

I never had problems with archive invalidation
I downloads all the files put them into nmm like gopher did
I installed it
I got the nice textures & the fallout opening screen with nmc textures
everything got retex but the roads
