For a couple months now, whenever i open certain drawings, i get a message that pops up saying i'm missing styles. So on friday, i decided to reload my profile. i did so and everything was working fine (the missing styles message was still popping up in some of my drawings but nothing was MISSING or running wrong. Came in on Monday and when i attempted to open Civil 3D, a message popped up saying my profile doesn't exist and Civil will open with its standard settings. i let it and immeadiately tried setting MY profile as current. it worked, but now most of my LISP routines aren't working and when i go to use my modify>pipe networks i can't get any pipes or structures. i'm sure there are more things missing that i haven't discovered yet but those two are the ones i was attempting to use right now. how can i fix this without having to re-install autoCAD?
