Cannot relogin into Viber

I had a Viber account only on my Android pad. The app crashed every five minutes so I've deleted it from the device. After that I've installed Viber through Play Market. When I am entering my cell phone number to log in, it writes that it has send the code to my device via Viber. But I do not have Viber installed on my devices! Can I re-enter Viber using this phone number again? Please, help!
