Hey Sita...I applaud your bravery but I'm not sure how anyone expects one to get answers if one never asks questions, correct?
I just thought I'd let you know that I too am running service pack 3 with no problems. You can open your resource.cfg file with notepad and it should look as follows:
Priority 500
PackedFile Mods/Packages/*.package
PackedFile Mods/Packages/*/*.package
PackedFile Mods/Packages/*/*/*.package
PackedFile Mods/Packages/*/*/*/*.package
PackedFile Mods/Packages/*/*/*/*/*.package
If not you should download a new one. This is the resource.cfg in C:\Program Files\Electronic Arts\The Sims 3 (or whatever your directory is). Then you should be able to put hacks in the hack folder if you like. I put AM directly in the Packages folder, I have a folder called NRaas for Twallan's cool stuff and all my other mods are in the Hacks folder. I have subfolders in my Misc, Build, and Skins folders and everything works great.
Hope something here might help.
