expstart.exe error on startup

[Advy]

So I applied an icon pack with 7tsp and now I'm getting an error with expstart.exe each time windows boots up.
The error states the following: (giving me 3 errors)
expstart.exe
Failed to update BITMAP '6801':24
Failed to update BITMAP '6805':24
Failed to update BITMAP '6809':24

So I've got no clue how to get rid of these errors, any help is much appreciated.

Thanks beforehand!
