Dear Players,
Many players have been experiencing crash issues while trying to play UNO online with Bit Defender anti-virus. We have identified the issue and are working with the Bit Defender team to fix it. This fix should be available before the end of March via an updated of BitDefender software. In the meantime, players can create an exception for UNO in the Active Threat Control by following directions at the link below. We will provide another update when the software update is available. This includes both Free and Paid versions of Bitdefender 2017.

Uno Dev Team
