I've checked S* upgrade quota(EVA) via (Awards/Star Alliance) and JP-ANA-Sp1 from KVS with Platinum membership in a PC Windows7 without any problem for 2 weeks. Suddenly, I couldn't anymore and this message appears-->Engines/MSIE Cookies Error [SF1-BSY].

I looked at KVS compatibility page and it seems like the error should come from the crossover MAC or other systems, which is not installed in my laptop.
