[Cura 15.06.03 - Not Slicing or Calculating or Saving]

So I kept fiddling around and have found a solution that appears to have worked:

With the win 64 Nov 17th Cura Version installed

-Close Cura

- Delete all files in:  C:\Users\user\AppData\Local\cura

- Restart Computer

-Re-Open Cura

Then hopefully it should work!

[Cura 15.06.03 - Not Slicing or Calculating or Saving]

To add to the mystery, I uninstalled the version 15.06.03 and downloaded and installed various versons of 15.10. From:

http://software.ultimaker.com/Cura_closed_beta/15.10/

Win 64 Nov 1st version - The model is perpetually slicing (even really tiny models)

Win 64 Nov 17th version - The issue is the same as described in the original post

Could there be some user setting that is being brought to the different versions?

Further experimenting on a different computer using the same stl files and 15.06.03 versions of Cura have worked. Which makes me think the issue is something local?

[Cura 15.06.03 - Not Slicing or Calculating or Saving]

Yesterday Cura was working fine, however today it is not working...

- Models Loads correctly and shows in solid view.

- However, Cure then does not calculate

- Layer view is blank (sometimes shows blank layers 0-11)

- Save button is grayed out

I have tried reinstalling, restating and various models including models I have previously printed successfully.

Engine log is blank in Help > show engine log...

Similar Posts have indicated that it is an antivirus issue on CuraEngine , but this appears to have installed correctly and Cura was working correctly until today so I do not think it is an install issue?
