problems with penumbra collection

[Zuitana]

okay the root of this bastard of a problem is that i do OWN both, plague before i got the penumbra collection.
however, the blackbox.dll crashes before you can actually get to the freezer and/or soon after if you literally try to grab anything, such as a board.
however, you can progress to the computer room up, get the saw, and get the hand. (don't ask how that was made possible) however, the penumbra collection is a 1.0 version and refuses to be completed cause the hand does not appear, when you give the saw in the computer central. but blackbox doesen't seem to go apeshit every 2 secconds. now i tried patching these bastards over and over a million times. fact: if attempting to rewrite the folder where is black plague installed, the game reject both, collectors and black plagues disk. due to authentication issues. and thus the game is uncompletable in the collection. any ideas how to get around this problem?

EDIT:
oh i also forgot to mention, if attempting to play the game with either, patched, or blackplague or collection installed and either of 1 of the 3 is present anywhere in the whole comp, the game keeps crashing refuses any kind of co-operation and effort to completing it.
