@Cyberek:
Thanks a lot for the link. I followed the instructions in link, but I still have problems after renaming the template.
After I renaming, the installation with the new template name does not appear as the original - there are some images missing and some links shrank.
I even searched around and found this and followed the instruction for updating the database - still the same issues:
