"my XDA exec PDA running low memory?

i have my newly gift XDA exec from my wife last xmas. but it seems i have a rough of using it.. even though i brought a 2GB storage memory card to store all my datas on it but it doesnt help..

Pls.. i need some help..

i get that message all the time. it's running low on physical memory, not storage memory. they're two different things. you'll normally run low on physical memory when you have too many programs open at once. if you don't, just restart it
