Hi @dan,

The trial version is considered as a full version of Pix4Dmapper just for a short period of time.

That means you should be able to do any actions the software offers.

In our system, I see that you are logged into Pix4Dmapper Discovery version, not to the Trial.

Therefore, please do the following:

1. Log out from Pix4Dmapper. Learn more in: [How to log out Pix4Dmapper Desktop](https://support.pix4d.com/hc/en-us/articles/208469726-How-to-log-out-Pix4Dmapper-Desktop).

2. Log in again. See more in [How to log in Pix4Dmapper](https://support.pix4d.com/hc/en-us/articles/207948656-How-to-log-in-Pix4Dmapper).

3. Choose the available trial license, not the Discovery Mode.  

I hope it helps!

Cheers

Yes, if the .p4d file was created in the Pix4Dmapper Discovery mode.
