i keep getting the same error message

memory space is low. please quit now and allocate more memory to pro tools.

ive tried every thing but still no luck.
im running a G4 silver with 256k ram a 3.2 Gig drive for system & a 57 Gig drive for audio data.
do i need to upgrage my ram ? if so by how much.

if you only have 256 k RAM, then yes upgrade it. I have 512 MB RAM and i'm going to double that as soon as i come into some money.
