A temp work around I've found is to use I.E's "in privet browsing"

I've got a problem with video playing on GS it either doesn't appear at all or its a non responsive black box can someone help, and I know its limited to this pc but I've made no changes to my net settings or updates to IE I was able to get it working for a while when I disabled and re-enabled adobe flash player

Any help plz?
