[Help... Migration mistake]

I developed some Windows forms with the trial version, now that I installed the developer ChartFX software two errors appear:

Object of type 'ChartFX.WinForms.Adornments.GradientBackground' cannot be converted to type 'ChartFX.WinForms.Adornments.IBackgroundAdornment'.

and

Object of type 'ChartFX.WinForms.Adornments.ImageBorder' cannot be converted to type 'ChartFX.WinForms.Adornments.IBorderAdornment'.

this mistake does not let me see the designed form I created, just the code, how can I fix this? Please help

Thank you
