Did you perhaps mean update 9, rather than up to 8? If you indeed meant update 9, you need to drag and drop it twice. See:
3. Drag and drop the downloaded file into the Project Dashboard and restart the program. First time!
4. Drag and drop the downloaded file into the Project Dashboard and restart the program. Second time!
Looks like a Java problem. Looks like a job for Igor!
Are you sure CT is using the correct Java to launch? Do you have multiple Javas installed on your computer?
Check which version of Java you have installed @ Control Panel\All Control Panel Items\Programs and Features
Uninstall them all.
Go to: http://www.java.com/en/download/manual.jsp and install the correct one for your computer
If possible, get the 64-bit version.
Try to start CT by double-clicking Start.jar.
You can also try right clicking on Start.jar and selecting Properties.
Look under: "Opens with ..." (change if needed, by clicking "Change").
Hello CT users,
I'm not sure what happened here. I was interested in update 8, downloaded it and installed it with drag and drop -> Installation complete. I quit CT and now it doesn't start anymore, doesn't react at all... Any suggestions?
