dotTrace 5.5 SDK with floating license

Hi, I want to use the dotTrace SDK with SelfAttach in our product. I use OpenProfilingConfig with ProfilingControlKind.ControllerWindow.
We work with a floating license for dotTrace.
Now, I can start profiling and then get the snapshot using the interactive controller. However, when dotTrace wants to open the snapshot, the following message box appears instead: "Current license does not permit to open snapshots produced under a more extended license". Does that have to do with the floating license? How can I get around this message?
