Bug Fixes

• Fixed an issue where ESET antivirus caused a fatal error in the Engine client. If you are using ESET, some Engine features may not work properly until they release an update to resolve this on their end. In the meantime, info on how to resolve the issue manually can be found here.

New Firmware

• Rival 300 - Fixed an issue that was causing intermittent disconnections and/or an unresponsive sensor for some users.
• Sensei Wireless - Fixed a sleep issue when the mouse is in wired mode.
