Needless to say, I need

. I did a system restore, and now when I try to load my Calibre, latest version (2.?) I get an error message saying:
Python function terminated unexpectedly
Failed to load icu with error: MemoryLoadLibrary() failed loading icu.pyd (Error Code: 1)
I am willing to reload my Python, but which version do I need for the latest Calibre? Also, will that fix the problem?
I went into my Uninstall/Repair and tried to repair my current version, but no change.
Right now my Calibre won't even load.
