No such file or directory error after 7.1 update.

[Agent Orange]

I have had no problems updating my sites with XWDP 7.0. After updating to ver 7.1, I can no longer update my site. When I save and then export my site and then try to publish my site I get this error. " /index_htm_files: No such file or directory "
That directory is still on my site as I can see it with FileZilla.

As a test, I saved my Xara working directory (mysite.web) site to another location on my hard drive and changed the upload directory in XARA to another of my web domains. I set up the new site's address in the PUBLISH preferences and then , saved, exported and then published the site. That worked with no problems.

So, I can apparently publish to a new empty domain, but I can not continue to use ver 7.1 to update my existing sites.

I am running Windows 7 home premium 64bit.

Any help will be much appreciated!
