I followed the steps from an old topic but still does not work.
I ran the generate.cgi on "Publish", then it returned the message: "Please wait while your store is generated ..." the process ends however it still shows the same message, when I go back to the publish section it shows the alert: "A previous regeneration did not finish!"
I followed the steps to complete a clean regeneration deleting the files update.dat , update_i.dat , progress.dat, however I did not find the progress_i.dat file, and when I start to generate, it gets stuck once it has reached around the 15% of the progress.
