Have you tried to go to Control Panel > Mouse > Pointer Options and to chose a theme from the drop box (I'm not sure if the pack creates a theme or not, but there maybe one
)
If you can't find a cursor theme there, you might also be able to find the actual tux pointers in one of the subfolders of the "Bricopack" folder located in your Windows installation directory (usually C:\WINDOWS) 
You might want to try this before reinstalling the pack in safe mode, it seems to me like it's less troublesome
