Invalid ChartFX License 03800000

[User (Legacy)]

I'm developing a web form application using the developer studio version of 

ChartFX (6.2).  I subsequently installed a full license version of a ChartFX 

for winforms (v 6.0).  Now, although win form apps are fine, the web form 

app displays Invalid ChartFX Licence 0380000.

I tried uninstalling the ChartFX for winforms but still get the same thing.

What do I do to fix this?

cheers
