The new  PTGui v11 version does not support direct connectivity from the Mistika GUI yet.  PTGui version 10 works correctly, but if you need to use PCGui 11 please do the following:

- Open PTGui v11 directly, not from Mistika GUI.

- When saving the result select the export to PTGui 10.

In any case, we recommend to use PTGui 10 when possible, as v11 behaves differently and it may still fail in some cases.
