It could be a WU issue because i have been doing this for about a year and a half, and i don't see anyone else having issues. I am currently running it on a Lenovo T-540P (laptop) with Windows 10. I don't think its that, because i originally started by running it on a Lenovo laptop with Windows Vista and it worked just fine. It was working fine up until i tried those expansion modules, i uninstalled those because they were not working for me. Is there any other solution? Or am i the only one having this issue?
