TypeInitializationException-in-Building-Blocks-for-PriceGrid

Hello,
i have the newest Version WL8, Build 8 and PriceGrids doesnt work.

When i open a new Building Block Strategy and take from the menue ChartPatterns PriceGrid into the buildigBlock, this error-message appears:

"System.TypeInitializationException: The type initializer for '†††
†††–‘•' threw an exception."

Thanks for your help
