Indexhibit Support

Hi, trying to upgrade from old version. After uploading components, go to install page and get this message:
XX /files/dimgs/ folder not OK
XX /ndxzsite/config/ folder not OK
I updated permissions on ftp server for them (and 2 other folders/files to 755. What else do I need to do? Thanks -Howard

SOLVED!
Put back old ndxz-studio folder and Indexhibit was able to read the old settings. Also restored permissions on the dig and config folders to 777. Indexhibit wasn't accepting them w 755
