[Cura won't connect to my Ultimaker]

Sorry for the delayed response, I've been under the weather lately. Unfortunately I'm still having trouble connecting to the printer. Below is the error log from a failed print attempt:

[Cura won't connect to my Ultimaker]

Thanks Daid, I'll try this after work. I should probably uninstall RepG and try to "remove" all bits of my Ultimaker from my PC.

Should I approach it like I'm plugging it in for the first time?

[Cura won't connect to my Ultimaker]

I just installed Cura on my PC. I had been using RepG with my Ultimaker for about a year with no problems. I decided to upgrade to Cura and upgrade to Marlin.

When I run the activation wizard, it can't connect to my Ultimaker. The software runs fine, and lets me set up a model to print, but it can't connect. I've attached an image that has some of my basic driver/pc info.

Please let me know if you need more information to help diagnose my problem.

Thank You,

Dan
