MaryGladys, shame on you for not reading the posts!! I just answered this a couple posts back!
The tweaks enable Mass Storage Card mode which means that while it's connected to the PC, you don't have access to the storage card on the phone... just disconnect it from the PC... OR... go back to Start > Settings > Connections > USB to PC > and switch it back to ActiveSync.
UPDATE: I reposted the packages so that they use ActiveSync again instead of Mass Storage, it was starting to annoy me too.
