DFUTool crashes while Firmware Download [SOLVED]

Hello,
yesterday i updated my m6 firmware from 2003.2 to 2004.3.
Unfortunately i installed the TP-Version for my SP-Player and got a
permanent white screen after that.
I followed the steps from madman in this thread (position 4)
DFU Tools
to get DFUTool working, but the firmware uploading process failed because
DFUTool crashed.
Meanwhile my M6 just shows me a black sceen and still is recognised in Windows as an DFU-Server.
But everytime after pressing "Download" i get the Status
"Manifesting image 1" and after that "Downloading image 1" and then DFUTool crashes again.
I tried DFUTool with Firmware versions 1.010SP and 2004.3SP.
Can anyone help me, to get the DFUTool running or is my player hopelessly gone?

Try reinstall dfu tools and the dfu driver!

Thanks for your reply!
I just reinstalled the DFU-driver and DFUTool several times- no changes.
I see a full blue progess bar while "manifesting image 1" but no progress bar while "downloading image 1".
DFUTool doesn't crash immediately, but after ~3minutes i see the "no response" notification in the title bar.

The no response is only made by windows if a program doesn't handle windows messages for some time. I haven't used DFU tool yet, but it COULD be just that the program's busy sooooo long.
However, I'd recommend you try on an other computer, preferably with Vista, where you can simply copy the correct firmware on the player without needing DFU tool (as far as I've heard that)..wysiwyg { background-attachment: scroll; background-repeat: repeat; background-position: 0% 0%; background-color: #f5f5ff; background-image: none; color: #000000; font-family: Verdana, Arial, Arial; font-style: normal; font-variant: normal; font-weight: 400; font-size: 10pt; line-height: normal } p { margin: 0px; }

Thank you for your help, i tried the firmware upload on another computer and it worked!
