When updating an HSQL database to run with QPS 8, the file path needs to be correctly defined within the QPS 8 Update Script, for example, './HsqlDbSchemaUpdator.sh '/Applications/Quark\ Publishing\ System/QPS\ Server/database/hsqldb/.'

To update your Hsql path for QPS 8, update the path to the Hsql database in the QPS Update Script.
