I just bought a Clothworks license however I can't find the license in my licenses php on SketchUcation web site till now. It have been over 8 hours... what I shall do now?

Besides, I still can't activate my clothworks use the file which you mail to me. I already install Sketchucation tools V4.2.6 , what else I can try now? The error code is A0B
