S.T.A.L.K.E.R. Lost Alpha bugs & modding Thread

I'll continue off the original post I made on Dez0wave official youtube site the loss of text, ammo count and such are what I believe to be the effect of trying an unpacker and it opened gamedata files 4 & 5 with Windows media player wich has been fluctuating on how many Kbs (1,450,146/1,436,325) to sometimes 0Kbs. I uninstalled and reinstalled the whole game 6 or 7 times now and it still makes those two folders Mediaplayer, including patch 1.3003. As for the unpacker I will admit not knowing how to implement them, never had to for the three STALKER hard copies I own (SoC/CS/CoP). I ran them found the patches and mods and played. No unpacker needed. When I tried to make a blank gamedata folder it told me I do not have administrator permissions. Hope you can help.
