Visual Explain for DB2, no access plan

[jfnorris]

I'm having some difficulty with Visual Explain. When I explain reletively simple sql, VE will generate an access plan. If I try to explain sql with several joins both outer and inner, or anthing more complicated, the tool will act like it's processing the sql but does not generate the access plan. No errors or anything. Any Ideas?? Thanks in adavnce.
