IMovies keeps crashing in Yosemite

Question

Hi Folks,
Has any one recently upgraded to Yosemite OS and are having problems with iTunes and iMovies crashing when you open the program?
It doesn't even log in, I only get the Problem Report for iMovie box.
Any suggestions are welcome.
Cheers!

Try restarting your Mac in Safe mode:
- Shut down your Mac
- Wait until your computer turns off and after that press the Power button
- Right after you hear the startup tone, press and hold the Shift key
- Release the Shift key when you see a grey Apple sign and the progress bar below this sign
- Once you see Desktop, start a Disc Utility scan to detect and repair file system errors (don't forget to choose your main hard drive)
- Click on Verify Disc and then, if asked to fix problems, on Repair Disk
- After this, click on Verify Disc Permissions and then on Repair Disc Permissions
- After the process is finished, shut down your Mac and turn it back on after about 30 seconds
You can also try to do this:
1. Go to your Library (open the Go menu with the Alt key pressed)
2. Go to the Preferences folder and locate the file called "com.apple.iMovieApp.plist"
3. Move this file to your desktop.
4. Restart your Mac and try to open iMovie once again.
Hope this will help
