[atlas] How to get a new USB stick ?

Hello, The SanDisk USB (4GB) provided with the RIPE Atlas probe don’t work anymore since more 5 days and the connection logs say “NO USB”. To check the USB stick, I plugged a personal one and since this time the probe is working again. I have this probe number 18685 since 2015-03-05. I would like know if the team could send me a new USB stick to replace the old one please or if I need to buy a new one myself ? Best regards, Élodie
