.vcd file generation

Oh, so frustrated.... I need help, anyone? :(

Problem is the following (and I am going in circles it seems):

I am trying to do power analysis using Quartus II power analyzer. I create .vwf file and perform functional and timing simulation and obtain a .vcd file that I use as input to power analyzer. And everything is fine.

Problem occurs when someone else who is doing paralel power analysis on a same module (using Xilinx xpower) sends me a testbench and appropriate .vcd file (created using Xilinx tools). In order to compare our results I need to use given .vcd file. In order to perform simulation in QUartus I need that .vwf file.

My question is how to go about this? Quartus simulatior needs .vwf file in order to generate .vcd. I cannot skip this process since I am doing power analysis.
