What the F*^% I'm runnning a Xdv pp on a 10.2.8 osx I was cruising along working on a project and all of a sudden my space bar stopped playing in my timeline. I had just applied an effect, and it stopped working. I can't get it to play on my timeline, or in my composer window. I undid the the last action, the effect, and it still doesn't play. but get this, if I click on the sequence from my bin, it will play the sequence using the space bar, and the cursor will follow on the timeline. Hey, I know my shiite is old, and I plan on updating immediately, but the problem is that this happens even when I open other projects, I can't get my timeline to play within the application at all. WHAT THE F*^%. SOMEONE PLEASE TELL ME WHAT'S GOING ON. don't log it on this blog, hit me on my hip and tell me, I'll even pay for the call. 832 418 9827 Tony. Call me. I've even tried reloading the application, and it still doesn't work. It makes me wonder if upgrading is going to do the trick either.

Calm down please,

Let's start with the basics:
Could it be that the timeline or the Composer window are lapping over onto the edge of the Monitor?

If you want help, it will have to be here. Neither Tech support nor Moderators of this forum will give you free phone support for this problem. Also, when asking for assistance here, please moderate your language and try to state your problem calmly and completely.

new user settings?

Try rendering all of the effects in your timeline.

Rebuild site settings files, they may have become corrupted. Quit the application, and from the "settings" folder, delete the following: MC State, Site_Settings, Site_Attributes. On re-launch, the system will detect the missing files and build new ones. If you had previously dragged any user settings into the site settings window, those will need to be restored after the rebuild.

Just now noticed that this thread is 5 years old. I doubt the OP is even still around.

Yep, the OP has 1 post - maybe he's still waiting to get that phone call?  I wonder if the # is still valid?  We could have lots of fun with it.

...maybe he's still waiting to get that phone call?

I'm picturing in my mind a human skeleton, his arm propped on a table at the elbow with chin in hand, covered with cobwebs, staring intently at a phone, also covered with cobwebs.

lol.
