Crescent Nebula-Ha-SHO

I am trying to refresh my skills, but feel really rusty. I got a very nice set of fits files but wasted few hours trying to register images. For some reasons DSS (I upgraded to 5.1 version) register the files but they disappear, I cannot find them. Normally registered files should be in the same folder as final images but they are not.... The program shows successful registration and even stacking but , there are the registered files, God knows. I also tried Maxim 5 but again failed. Aligning files are problematic even manually with two stars, getting double stars and unclear image. Somehow I managed to align the images but not perfectly. I cannot use PI (my laptop will not survive this software), but old soft does not work well for me too. Any ideas?

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
