It's a great player which plays all major format.

But yesterday, i don't know why, but it stopped playing RMVB format. I had played one RMVB clip few days back on GOM, but yesterday same or other clip would not open. I tried to re-stall it also, but same issue.
Last major updation, was installing IE 8.

If someone can tell what may be issue & how to overcome it?

Thanks
