hi! i have a BIG Problem...i update the Commerce Starkit and edit the Commerce.mdf database,its ok in my pc but once i transer the files to another computer it does'nt work.
here is what i do to transfer the files from my pc to another pc, i copy the modified Commerce Starkit and paste it to

c:\Intepub\wwwroot (from another pc), then i copy the Commerce.mdf and Commerce.ldf from the MS SQL folder, then paste it to another pc with MSDE also installed.
