Re: Checksum mismatch creating repository?

1) "Is this a verbatim copy of the error or is this for various values of
#FILENAME#?"
Various values.

2) "Why are you importing anything there?"
We cant use a dump file, cause we dont have it. But I think it is not
important, because the 'import' should work.

3) "Actually, I'm still not sure what exactly you did and on what machines."
    a. I installed subversion
    b. used "svnadmin create name # #"
    c. used svn import-m "message" http:// servername # # / # # name /
Simple! This steps work on a Windows 7 Machine!
