Thank you so much for reaching out to us, I am sorry to hear that you are running into this issue, but I would be more than happy to assist.
Just to make sure we have all of the right information, could you please keep everything connected and send us the output of our diagnostic utility PlugDebug --> http://plugable.com/support/plugdebug as this will allow us to examine some log files from your system. Once the program completes, please attach the .zip file located on your desktop to a direct email, and send it to firstname.lastname@example.org. Please include “Ticket no. 210012” inside of the subject line.
Then, once I again review the log files, we can attempt to send over some troubleshooting steps to resolve the issue.
Thank you for your patience,
Product Owner & Technical Support
