Eclipse error after moving project (No resource found that matches the given name)

Question

I had a perfectly working project of an app on android. It uses actionbarsherlock. I moved using the refactor menu in eclipse to another folder and now I have problems with the styles.xml

No resource found that matches the given name 'windowActionBarOverlay'

As I said, the project worked well before moving it so I think it has something to do with the build path.

Restoring it to the previous folder doesn't fix the problem.

Thanks a lot!

Styles.xml

    <resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>
