Sprint: AIM not forwarding msgs

[xunknownx]

usually on AIM, you can txt ppl using +1 area code + phone number.

for example +1415XXXXXXX

i dont know what happened but it can be caused from switching to the touch pro. its prolly around that time when this stopped working.

now everytime wen I, or someone else try to send me a txt thru aim. we receive a "Your message could not be delivered. Please try again later."

i went into AIM settings and made sure the option is enabled. but it still doesnt work. any one else with this issue?
