Hi Reuben,
I don't know what that error is. There is no format folder beneath trunk.
The only thing I can guess is that you originally got the source from svn when svn at Novell Forge was using ssh for anonymous access. They no longer have anonymous ssh access so you have to use https instead.
When they made this change at Novell Forge I updated the instructions here:
http://www.mojoportal.com/tortoisesvn.aspxYou should right click the top level folder and choose TortoiseSVN>Relocate
if the url is this
svn+ssh://anonymous@forgesvn1.novell.com/svn/mojoportal/trunk
then change it to this
https://forgesvn1.novell.com/svn/mojoportal/trunk
Hope it helps,
Joe
