I can not receive text messages after install Pocket Legends

Hi everybody, I am a new player, just got the game yestarday.
I found something really weird, after I installed the game I am not able to receive text messages. I am playing on a GSM Motorola Milestone and I am able to make calls and send messages, could you help me to fix this?
I am really excited about the game, but I will not be able to play it if my phone will lose the text messages property, I think this is a big issue, and I do not know how to fix it.
