Since I upgraded TortoiseSVN to the latest version (1.7.11) on both my laptop (Win 7 x64) and desktop (XP x86) I lost my custom SVN columns in xplorer2. (I lost them in XP's Explorer too, which is why it has to be a TortoiseSVN problem).
After a couple of weeks of trying to trying to make do without I finally found this thread which indicates that it's a problem with the TortoiseSVN installer and provides a workaround.
I've copied the text of the workaround below; it worked for me in XP x86 and hopefully the same will fix my Win 7 x64 installation.
If you create this registry key (note: key, not value), it should start working again:
I don't know if the change was intentional but when I looked at the installer scripts in svn they still looked like they were supposed to create the key, so maybe something is failing in the installer before that point. (Or maybe I just missed a detail and the new installer is functioning as intended.)
Adding that key by hand made the columns work again for me when testing in Windows 7 x64 (using a file manager that still supports IColumnHandler on Win7, not Windows Explorer).

Thanks!
This worked for me on Windows 7 PRO SP1 64bit.
I created the registry keys, killed the xplorer2 process and started xplorer2. The columns are now available
