Ugly noise from Waves Doubler when used in Pro Tools

[hooksound]

When Waves Doubler is selected on an insert it emits an extremely ugly maxed out random noise. A few of the patches seem to work and it seems to work with Cubase (Studio 4).

Any of you guys out there have the same problem?

I contacted Waves support and here's the full repair procedure:

1. Go to: Start Menu > Settings > Control Panel.
2. Select Regional and Language Options.
3. Click on the Customize button.
4. Make the following changes:
Decimal symbol: . (dot)
Digit grouping symbol: , (comma)
List separator: , (comma)
Negative number format: -1.1

Issue is that Waves stuff is only fully supported under English (US). Furthermore it was stated that this is a very old known issue. Maybe it is time to make a correction then?
