Moving file failed-Ubuntu 12.04 - PlayOnLinux

I’m having problem with this one. Im trying to solve this for the entire day but not lucky. I installed the unity in my ubuntu 12.04 through playonlinux. Every installation is finished, and i tried to create project, this error always prompt. and when I close the unity and open it again, same error will appear.

thanks

I already solve this issue, i just upgraded/set my PlayOnLinux to the latest version. Before, my PlayOnLinux was in 1.4 then change to 1.7.17
