Sending an SMS with the new dashboard software

[SarelSeemonster]

I've managed to send SMSes before with the new dashboard software, but now I just get:

Exception while handling sending sms
class util::AtTimeoutEx | 0 | Timeout while waiting for AT: 05917228199211010A81804226697000110B05D4F29C1E03. | .\WWanDevice.cpp | ace::WWanDevice::Transact | 217

Stack Entry | 0 |  | .\GenericWWan.cpp | ace::GenericWWan::SendSms | 2826
Stack Entry | 0 |  | .\DeviceManager\DeviceManager.cpp | ace::DeviceManager::SendSms | 1252

I've tried to disconnect/reconnect the speedstick, didn't help. My Internet connectivity is just fine. Check balance tells me:

Balance = R 100.00 Expiry date:14/08/2012.Free Data = 0.01 MB.Free Data = 2195.79 MB.Recharge Reward SMS = 100.Recharge Reward MB = 0.02 MB

Any ideas?
