This would be an fantastic app. But unfortunately it dosen't send any sms on my device. Everything seems to be fine, but my contacts don' get any message I send with this app.

Am I doing something wrong? Could anyone help me please?

Thanks in advance!

Edit: Now it seems to work for groups, that have just one contact. For groups with more contacts it opens conversation and the "wheel" in the status bar spinns while the conversation window keeps empty/black. Then conversation window closes. Finally no sms is send.
