Hey Pablo,

I would suggest trying to disconnect from the internet and attempt to open up the software offline. After opening the software you can connect to the internet again.

If this does not work, please&nbsp;uninstall the software following the instructions here:[How-to-completely-uninstall-Pix4D-Desktop&nbsp;](https://support.pix4d.com/hc/en-us/articles/360000450103-How-to-completely-uninstall-Pix4D-Desktop)

_Then reinstall the latest software version: [https://cloud.pix4d.com/download/](https://cloud.pix4d.com/download/)_

Please let me know if you are able to access the software.
