[xwiki-users] XWiki newbie question

Latest version of XWiki Enterprise MS SQL 2005   JSQLConnect JDBC Driver Tomcat 5.5.28 The initial database gets created but when I try to import the following xar file xwiki-enterprise-wiki-2.2.1.xar I start to get the following error Wrapped Exception: com.jnetdirect.jsql.JSQLException: The data types varchar and ntext are incompatible in the equal to operator.         at com.jnetdirect.jsql.JSQLException.makeFromDatabaseError(JSQLException.java:85)         at com.jnetdirect.jsql.IOBuffer.processPackets(IOBuffer.java:547)         at com.jnetdirect.jsql.JSQLConnection.prePrepare(JSQLConnection.java:2620)         at com.jnetdirect.jsql.JSQLConnection.getPreparedStatementHandle(JSQLConnection.java:2553)         at com.jnetdirect.jsql.JSQLPreparedStatement.executeQuery(JSQLPreparedSt atement.java:359) Once this error has occurred, any interactions from then on essentially generate the same error. Is there something that I am missing. I'm assuming that somehow the initial config needs to be told how to create columns using ntext and not varchar I can skip importing the xar file for now but I rather like to use some of the features What I am really after is to disable registration and add the users manually with appropriate rights.  Any help would be appreciated
