Logic missing sample files

Hey everyone, I'm having an issue that I've been unable to resolve...

I use Logic on an imac and a macbook, and the imac seems to be missing some sample files, while the macbook is fine. More specifically, it seems to be the EXS 24 instruments that sometimes are missing their samples, I get warnings when loading certain instruments that Logic can't find the AIF sample for that instrument. Here's a specific example: the Steinway piano always tell me that I'm missing Stw ped v1 024.aif.

So I have a 2 part question.

Part 1) Suggestions on how to fix this... I've considered just reinstalling Logic, but that will take time... which leads me to question # 2:

Part 2) I figured a simple solution would be to find the missing AIF files on my macbook and just copy them over (I screenshot each missing file message). Sound good in theory right... but... OS X (Mountain Lion) will not let me find the files anywhere... I figured they might be hidden, but even with my files unhidden I can't find them, either manually or with spotlight. Is there a way to get spotlight to search for hidden files? I assume so...

Here are some AIF's the are "missing" from the iMac:
YT2-SHWDSKX01_2ue
DC Tit Hat 08
Stw ped v1 024
APicA f atk d1x c#
IL Btl Bass bomb 08
DC Tit Hat 08
megapadchordz.01

Even if I could at least find them on the macbook, that would help...

Any help that anyone can provide would be GREATLY appreciated... Thanks!

Sorry for the late follow up. Did you fix your issue curlydog?

I did manage to fix it but only by redownloading the sample packs individually (I redownloaded them a few times prior, but all at once, and that never helped). And I never could find the actual sample files. Even when getting the system to show hidden files, etc. Kinda weird...
