need help iOS 4.1 can't mask apps icons

[Romeo26222]

Hello
I was on 4.0.1 and using winterboard to auto create apps icons mask
files i made were
AppIconMask.png
AppIconOverlay.png
AppIconShadow.png

and they were working good with all apps
now i upgraded to iOS 4.1 and this masking no longer applies on any icon!!
I guess there is some changes inside this FW maybe file names or something i can't figure out..
any help for applying these masks again on my 3GS iOS 4.1?
regards

Downloading iWipeCache worked for me, after setting up your theme run iWipe and respring should work
