Keil::STM32F4xx_DFP V2.11.0 to V2.12.0 upgrade issue

Hi,

I am using MDK-ARM V5.17 and recently updated from Keil::STM32F4xx_DFP V2.11.0 to V2.12.0.
When I start uVision I now get the following error:

"Loading PDSC Debug Description Failed for STMicroelectronics STM32F437IIx. Disabling usage of PDSC Debug Description. See Build Output for details."

The build Output windows shows the following:

"
File : C:\Keil_v5\ARM\PACK\Keil\STM32F4xx_DFP\2.12.0\Keil.STM32F4xx_DFP.pdsc
Sequence : CheckID
Context : Item #1: <control if="jep106id != 0x20"> Item #0: <block>::Line 2
Expression : " Message(2, "Not a genuine ST Device! Abort connection.");"
----------------------------^
E203 : Undefined identifier - function 'Message'"

Any ideas how to solve this?

Thanks.
