(Redirected) Power director stopped working for no reason - error message

Hello everyone.

I wonder if any one can help me.  I have anew computer Dell 17 5570.  it came with the Dell media suite but the Power Director has just stopped working for no reason.  I get error message that windows cannot find it.  I have not deleted anything or anything like that.  Can any one suggest how to get it back? has anyone else had this problem?  I tried system restore but even that did not work properly (said restore was not complete!?) so that did not help.  

Any help would be appreciated.

Thanks.
