@Eroico it means your account is banned by whatsapp by some reason. write to whatsapp support to solve this problem. @Iceman_709 maybe "stale" not "Slate"? It means your sms code too old. Try again tomorrow. @sardanis how you installed application? i mean what method? clicking on deb file in filemanager, in terminal via dpkg or gdebi, or via some repository (openrepos)?
