Downgrade Bootloader by XDAtools is ERROR ???

[VHS]

I tried downgrade Bootloader by XDAtools but no success. It reports:
************************************************** *******
C:/Program File/XDAtools/binaries>pnewbootloader bootloader_v5_15.nb0
'C:/Program' is not recognized as an internal or external command,
operable program or batch file.
ERROR: ITReadProcessMemory - Unspecified error
Unable to find flash info offset, cannot disable bootloader writeprotect
************************************************** *********
I caught sight of them in my screen

My PC run: WindowsXP SP2, Activesync 3.17, XDAtools from Jeff
My XDA run: T-Mo 4.00.10, RS 4.21, Bootloader 5.17
I installed XDAtools then run "Fix broken bootloader" from program.

Any idea???

you found a bug. I'll fix it when I find the time.
meanwhile you may work around it by putting your software in a directory
which does not contain a space in the filename.
