Before you post your question, PLEASE gather the information I need to answer it.
Here is a post that outlines some useful diagnostic information:

If you actually read that, and post what it asks for, I promise you this:
1. I will give your support request priority over people who do not post this information.
2. I will be able to solve your problem more quickly.
3. It will require fewer posts to solve your problem.
Do you know how many times I have to ask "Joomla version? PUArcade version? PHP Version? etc..." in response to forum posts? If you just answer these questions straight away, it will save us all a lot of time.
Thanks!
