Do you get a blank page when trying to open extension’s page or you just do not see extension’s tab? If you get a blank page try to enable error displaying in “index.php” file of your Magento by uncommenting the following line:
I.e. you need to remove the “#” symbol before the line. Thus, most likely you will see the error which occurs when you are opening the page.
As for “Access Denied”, this is very often problem with Magento 1.4.x. I recommend to contact extension vendor and ask them about this. Most likely they met it before and can send you the solution.
Have a nice day.
