The new updater solved the issue, I launched it and it showed current version "255.255.255.255" / update version "188.8.131.52", then clicked update and now everything is back to normal. (just one thing the SparkLEupdater always crash when clicking cancel, Spark2.png).
Thanks again for your reactivity on this issue!
Remember to update the "Update Spark Controller" in the menu of Spark software himself, it's a bit confusing. (show screenshot in attach, Spark.png)
