The Acer w510 Iconia tablet will randomly lock-up while templating.
This is actually not an issue with the LT-55 XL software. It is instead an issue with some of the drivers that came shipped with the Acer w510 Iconia tablet. Drivers are what allow software to communicate with hardware. Since Acer has updated the driver package, we have shipped all Acer w510s with the following updates. If this issue is affecting you, it means the tablet was shipped out prior to the driver package update.
Download the following driver update and run it on your Acer w510. This fixes all known lock-up issues.
