Hello!

I've been taking a little pause for playing Fallout:NV. Now few days ago I reinstalled NV, and it worked well. Then I found that there's new DLC for NV, and installed those all. Now I have played few days, and discovered that I can't see anything with PIP-BOY. I can see frame, but not inventories etc. I can "hear" items when I move cursor around that black PIP-BOY. I can also use chems, change weapons and fast travel, problem is I can't see what I am doing.

I tried another save, didn't work. I tried to start new game, and found that I can't see even character's face when Doc want's to know how my character looks like. Then i tried to reinstall whole game again, but that didn't work either.

Can anyone help me with PIP-BOY-problem?
I'll be grateful.

E: Now I am trying to install it from DVD, not from Steam. By the way, it was litlle hard to find out how to do that... https://support.steampowered.com/kb_article.php?ref=5357-FSQM-0382
I can't understand why it wants to load from Steam and not from dvd. DVD has all the files needed to install the game, and I have quota on my connection which stops download for 24 hours, when it is "fresh" again.

E2: Installing game from DVD didn't work. Also I noticed that I can't see anything on computer screens while hacking. Still I got one hacked, literally blind...

E3: When I play from Steam "verify integrity of game cache..." it always brings message; "1 files failed to valitade and will be reacquired. And then it doesn't do anything....

E4: Marking or unmarking Data File sbefore starting game doesn't affect anything

Do you use any mods at all other than the DLC? Has the game worked in the past?

I don't have any unofficial mods, I only have DLC that I've purchased trough Steam. Earlier without any DLC game worked well. Well... as good as it get's... Then I bought Dead Money, at time when there wasn't any other DLC, and it worked well. Now, few days ago I purchased all DLC trough Steam, and it worked few days, I started new game, and I played it to Primm and was heading to that gas station between Primm and NCR Mojave Outpost when I discovered that problem with PIP-BOY. And I am sure I didn't get that far without noticing if there was problem with PIP-BOY. Same problem affects on every saved game, starting new game and inside or outside of places. Chancing HUD colour doesn't help either.

Thank you for your interest!
