Registax 6 Saturn vanishes after stacking?

[Space Cowboy]

After aligning and stacking in Registax 6 there is no image on the wavelets page....if I select "do all" Saturn appears for a second then vanishes again. Seems to happen when the LRGB box is ticked. Any ideas?

Because of this i'm sticking to Registax 5.1

I had similar problem with a lunar image. Nothing ata ll to see after stacking. Then, on further attempts, the image that did appear was misaligned and blocky- like a patchwork quilt! Worked fine for Saturn though for me. Registaz 5 had no problems with the lunar images
