You not only would need 7.0, but you would also need 6.1 as well. Version 7 can only save to 6.1 and version 6.1 can only save to 6.0. Even if you downloaded the 7.0 evaluation copy, I don't know if the 6.1 evaluation is still available for download. Your best chance is to post the VIs and hope that someone with both versions can do the conversion for you. You should also be aware that there are numerous differences between 7.0 and 6.0 and that a conversion might not even be possible.
