Have done so already
Thanks for the reply, I already tried dealing with the cache file, spent hours reading all the tech posts but to no avail. After uninstalling all the extensions except CSSMenu, I'm down to 3 errors in the Configuration/Floaters something or other. An end user shouldn't have to jump through all these hoops to get them working.
I have called 3 times and not been able to get a human, left detailed messages and no return call. I have emailed the Sales department and am awaiting a response. I'm hoping they refund my money and credit part of it to the CSSMenu.
It was almost like these extensions weren't tested properly prior to release to allow normal people to use them with Dreamweaver. The CSSMenu extension works nicely.
