weird yellow m-powered 7.4 protools

hi all,this my first time using a site like this so go easy..
oh! i hope i’m the right area?
well,my issue is that i bought m-powered 7.4 in conjunction with a m-audio
projectmix,,,all is well but the pro tools screen interface is all yellow apposed to the more
eye friendly and more common grey,,also when start up,the m-powered protools is yellow not red,,the strange thing is for about a week when i started up i got the red version,,this was great,lastnight it decided to become its yellow self again…

any idea’s guy’s
