Unable to Open Query Designer

Hi All,

I'm trying to open a query in query designer .... after selecting the query and click on Open .... I'm receiving a message "This componet was edited with more recent version of a editor. You also have to use the more recent version to edit further Further processing is not possible. Update your front end"

I know I need to upgrade ... please advise and me on this .... I noticed SAP Service market place ... I can't find one.

TQ
