Problem restoring a PowerShell backup

I had a problem today attempting to restore a backup I had taken using PowerShell.  I received the following error in PowerShell when running thr Restore-SPSite command:

"Restore-SPSite : Your backup is from a different version of Microsoft SharePoint Foundation and cannot be restored to a server running the current version. The backup file should be restored to a server with version '4.1.10.0' or later."

I checked my SharePoint version numbers against the server where I had taken the backup and it all looked fine. I took another backup in case the first one had become corrupt (even though I had already restored it successfully several times before). I rebooted and restarted my VM, but all to no avail.

In a last ditch attempt, I decided to delete 2 empty content databases that were set up on my machine, and created a new one to replace them and tried again.

To my surprise, it worked. So, if you have the same problem, try removing content databases (if you can).

Usability Testing

Browsing through some of the SPC2011 conference materials, I came upon a useful website that provides usability testing from the perspective of how a user would interact with your web design. You simply provide a web design image or HTML I believe and a series of tests are run to assess how your design is used by real-world users.

The click responses to questions about the design are grouped and displayed so you can see whether what you thought was a prominent design for something important actually does the job of attracting user interest.

It's not a free site, but a test is only $9 (about £5.70 at today's price) which is possibly well worth the pay-out to get some useful design feedback upfront of any development work.
