Tracfone ZTE valet crashing Android File Transer on connection to mas osx 5.8

[ajax2112]

Hi folks, new to this tech but I've followed all instruction I can find. If I connect to my comp (os 10.5.8) via PTP (cam) it opens my iphoto just fine.. but if I want to connect it to transfer music, etc (via MTP) the Android File Transfer that I downloaded begins to start up, then immediately crashes. If I connect it via "install driver" it starts up then tells me that there is no android device attached. Any help folks?

thanks in advance.
