Theme Studio 1.2 Help!!!! :( :( :(

ive tried to search most threads regarding theme development but i couldn't find the answers to my problem. anyways, ive downloaded theme studio v1.2, replacing my old version which was v1.14. ive successfully created my own themes before but with theme studio 1.2 ive encountered many problems.

---> theme studio 1.2 now offers more icons to change (e.g. icons on the messaging, settings...etc) but none of the new icons ive made, appeared on my 7610. only one icon, the "my folders" icon. why? :???:

---> also how do you make the "grid highlight" transparent? ive used masks, 9 bit masks.... but i wont seem to become transparent. eventhough when i checkout the theme in theme studio the grid highlight is transparent... but on my phone it isnt... this is very confusing.... :sad:

i'd appreciate any help from you guys. thanks =)
