We installed it easy enough. Changed the settings to do a test run to produce a site map with a maximum of 100 URL's. Failed due to lack of memory !
Tried everything to no avail.
Contacted support who needed FTP access to try and fix it. Bit dodgy giving out FTP access but we gave access limited to the install directory.
They failed to get it to run.
All gone quiet now after we told them to get it running or give us our money back.
