Hi, Thank you for the questions.
The ppk2 file is 684KB.
I´ve installed Power Profiler on C-Drive. There´s about 8.3GB space available.
I´ve chosen my D-Drive as a temporary directory, there´s about 167GB available.
As soon as I try to load the ppk2 file, an error occurs (see screenshot).
Here´s the log dump:

Hello JonasD27,
Thank you for the details.
To confirm, is this the .ppk2 file you are trying to open?

Could you please also share what is the Disk full trigger set to at the moment/when the issue occurs?

Yes, that is the file I´m trying to open.
Disk Full Trigger was set to the maximum of 10240 MB.
I´ve discovered the following: As soon as I set the Disk Full Trigger to a smaller value (e.g. 3000 MB), I can open the file without a problem. Is this behavior intended?

It is a bug. The Disk Full Trigger is checked against a different drive. That will get fixed soon.
Thank you for the report and helping us getting to the bottom of it.
