Don't worry. This is like the #1 most encountered problem in the past few months/weeks i've been reading the forums. What happened was that you did not run either tool, guerilla, sapien or HEK+ as admin.
To fix this, go to the folders with lock icons in windows explorer and there should be a new button in the window called "Show compatibility files". Click on that and all your hidden tags should be there (cut and paste it). Or, do a search on the tag names and the hidden files should be in a directory with "virtual store" in its name or something. That directory should be the place were all your hidden tags are.

"This is what happens when you have window UAC enabled. If you don't know what that is, it's windows's crappy version of linux's built in file permissions system.
Programs that aren't run as admin can't write files to some directories such as C:\Program Files\. Files that are written there are instead sent into a symbolic link under the virtual store\ directory.
Disabling UAC stops this action from happening so you don't have to run programs as admin and deal with files going into the virtual store directory in the first place.
Just saying, by the way. It's up to you if you really want to disable UAC since it is a security feature, but to me it's just a hassle in my opinion. I'm not even really sure how this is supposed to increase security in any way, soo yeah.
I guess if you reaally don't want to disable UAC but still want to solve the hassle with write permissions, you could also reinstall halo and hek into a non write protected directory like the My Documents folder and optionally add a symbolic link to c:\program files\microsoft games\halo custom edition which would make it as if the halo's root directory is in program files but it is actually in my documents."
