Unable to cast object of type 'System.Single[*]' to type 'System.Single[]

Hi,

I'm trying to connect to Multiframe via COM. The COM object (Multiframe.SectionList mySectionList) returns a single dimension array of type float with the first element of the array having index 1 rather than 0.
This is why I have to create an array with first index being 1 rather than 0 (see CreateArray)

class SectionListArray
{
        Array myDs;

        public SectPropArray(){}

        ~SectPropArray(){}
        public void Add(ref Multiframe.SectionList mySectionList)
        {
                int nMem = myMemberList.Count;
                CreateArrays(nMem);
                FillArrays(mySectionList);
        }
        private void CreateArrays(int nMem)
        {
                int[] myLengthsArray = new int[1] { nMem };
                int[] myBoundsArray = new int[1] { 1 };
                myDs = Array.CreateInstance(typeof(double), myLengthsArray, myBoundsArray);//Depth D
        }
        private void FillArrays(Multiframe.SectionList mySectionList)
        {
                myDs = (Array)mySectionList.D;
        }
}

When I converted from VS2008 to VS2010 there were no warnings or errors. The exact code executed perfectly in VS2008. The error message is Unable to cast object of type 'System.Single[*]' to type 'System.Single[].

I upgraded the code to VS2010 to utilise Parallel Programming features in .NET 4 but I may have to revert back to VS2008 until the problem is sorted.
