With my modem currently broken I decided to temporarily buy and use the Rogers "Rocket" stick. Now last week I lost it and got a replacement just yesterday, Now on the first one i could play WoW for 2 hours only using 10MB of my 500MB per month limit, but last night I played for 2 hours, like usual. Except this time it said that my 2 hours had used up 237MB. Is this happening to anyone else, or just a technical error?
