I used to use mpt 3.11 to upload mp3 tones, wallapers and such on my phone, and one day ago it stopped working, it wouldn't connect, i removed the modem, added it again, but nothing won't happen still, i remember when i first added, it saw several other usb hubs which used the drivers from the pst, now it just installs the modem and that's it, mpt no longer connects to my phone, and i can't understand why. It happened once more some time ago, and finnaly, i somehow managed to get it to work, i don't really know how, please help me on this guys/gals.
Try this...since it happened to me once... Plug the phone in first to the computer.. then open MPT...it worked for me.
