Hi there!!!
Like i said in the topic description, Ableton just erased the tool button in the interface of any Waves plugin that i drop on whatever midi or audio channels. I really don't understand how or when began to happen, but i need help to solve this as soon as possible because there is no way to open the plugin window and obviously can't edit any parameter of it.
You can see in the attached picture what i mean.

I use ableton suite 9 in windows 7

 

Weird.
If your Waves plugins are legit ( isns't it ?;-), there is no way that sort of things is happening. Which waves version are you using ?
Did you save this implementation before to reload it? Just to check …

 

Weird indeed. Doesn't the plugin window open if you hit Configure?

 

Maybe you have the wrong but installed? Graphics and icons tend to disappear if 32 bit and 64 get put into the wrong place...
