Turns out it helps to remove the destination folder completely before pasting from your dev system, thus ensuring that all older versions of the DLLs have been removed.

Problem solved.  Thanks.

I'm glad you were able to resolve your issue. Here is a link explaining, what the problem can be. Excluding the second point, the possible fixes could be:

• You have two versions of the the same DLL that are being loaded.
• Code in a DLL is conflicting with a similarly named piece of code located in the /APP_CODE/ folder.

It seems in your case it the first one.

Thank you for using our product.
