Compiling list files problem

[Sergio]

Hi I've create a list files with all users in my network to group them so that they have different permission to access in internet, now when I try to compile this files with squidGuard -C to make them db files doesn't happen nothing. I have already compiled other file lists containing sites and domains created by me without  problem but with this users files after launched the squidGuard -C command I don't retrive the DB files nor I get errors message. Can someone tell me where I fault in this procedures? TIA     Sergio Copetti
