Hi,
Sorry to hear about your problems with Crazytalk 5.
I'm a little puzzled by how you aren't able to close it if you can't open it in the first place and vice versa. Maybe the program had just stopped responding and needed closing from the task manager.
If you find the program unresponsive you can open the Task Manager by Right Clicking on the Task Bar and choosing Task Manager. Then select Crazytalk 5 and choose to End Task.
If you are able to close the program then you should find it will then open again afterwards as long as the Crazytalk executable has been cleared from the task list. A restart of your computer will also remove it from the task list.
If this does not help your problem then contact support for further help. You can use the support form to request assistance. Please give as much detail as you can about the problem and describe what you were doing when the problem first occured. The more information given normally helps resolve it quicker.
