hello all, today i noticed that the programs that i had installed on my storage card had non functioning shortcuts. so i took out then reinstalled the card and nothing. I could browse to it though, i then browsed from a program for a file and saw that i had now had a "storage card, and a storage card2". anyone know why this maybe be. and i have palm threaded sms installed and overwrote all the windows file, could i delete the program file folder without messing anything up, since it is default now if i needed memory space? thanks in advance. sorry for my ignorance and for being so lengthy.
