how to deal with this problem:votst.exe 0x7dd916d2 Most likely exception: 0xC0000005: Access vialation reading location at 0x000

guys:

i use the intel visual fortran on the vs2010 to simulate with matlab2010,i have configured related path and lib.but have the problen as this:

votst.exe 0x7dd916d2 Most likely exception: 0xC0000005: Access vialation reading location at 0x0000000000000000.
votst.exe  0x7dd916d2 There are unhandled exceptions: 0xC0000005: Access vialation reading location at 0x0000000000000000.

the program code :

      program testpf
       implicit none
        integer*8,external :: engOpen,engClose,mxCreateDoubleMatrix
        integer*8,external :: mxGetPr,engPutVariable,engEvalString
        integer*8,external :: engGetVariable,mxFreeMatrix
        integer*8 ep,TT,D,t
        double precision time(10),dist(10)
        integer temp,status,i
        data time/1.0,2.0,3.0,4.0,5.0,6.0,7.0,8.0,9.0,10.0/

        ep = engOpen('matlab')
        TT = mxCreateDoubleMatrix(1,10,0)

        call mxCopyReal8ToPtr(time,mxGetPr(TT),10)
        status = engPutVariable(ep,T)

        t = engEvalString(ep,'DD=.5. *(-9.8).*TT.2; ')
        t = engEvalString(ep,'plot(TT,D);')
        t = engEvalString(ep,'title("Postion vs Time")')
        t = engEvalString(ep,'xlabel("Time(Seconds)")')
        t = engEvalString(ep,'ylabel("Position(meters)")')

        read(*,*)
        t = engEvalString(ep,'close;')

        D=engGetVariable(ep,'D')
        call mxCopyPtrToReal8(mxGetPr(D),dist,10)

        print *,'matlab computed the following distances;'
        print *,'time(s)distance(m)'

        do 10 i=1,10
        print *,time(i),dist(i)
   10   continue

      !  t= mxFreeMatrix(TT)
      !  t= mxFreeMatrix(D)
        t = engClose(ep)
        stop
        end

thanks  a lot
