Dear all:

First, my computer is 64-bit.

Then, based on test25 of FAST,I change the floating fundation structure, by using ServoData/DISCON_OC3Hywind_win32.dll of NRELOffshrBsline5MW_OC4DeepCwindSemi_ServoDyn.dat, but when running hydrodyn, it says:

'Generating incident wave kinematics and current time history.

Reading in WAMIT output with root name “.\5MW_Baseline/HydroData/marin_semi”.

Computing radiation impulse response functions and wave diffraction forces.

```
FAST_InitializeAll:HydroDyn_Init: Error allocating space for the distributed dynamic pressure
```

forces/moments array’

Then I choose ServoData/DISCON_OC3Hywind_x64.dll ,the hydrodyn is passed, but there is a error in moordyn, it says:

Running MoorDyn (v1.01.02F, 8-Apr-2016).

I fail to find the error by my own efforts, so I sincerely seek help.

Thanks
