[Zope] Zope on cd-rom for Windows

Hello all, I made a small Zope application on a Mac (MacOs X), On a Win98 machine, I installed Zope and I replaced the Data.fs, Data.fs.in and Data.fs.tmp files with the ones I had on the Mac. It worked. But when I burned everything on a cd (following the instruction found at www.zope.org/members/jens/docs/zope_on_cdrom) BANG it didn't start complaining an error no. 13 file: [stacktrace snipped] G:\\GD\\var\\Data.fs.tmp Permision Denied What am I doing wrong? One more thing: How exactly do I set the -r flag? Like this: python z2.py -D -r OR like this python z2.py -Dr ?? Thank you so much Bye Catonano
