Converting a Classic Project Plan to EPP

Dear All,

                In Windchill Projectlink 10.1 F000 when I am converting a Classic Project Plan to EPP then I am unable to Create new

Activities. When I create new Activity the Page is comes blank and there is only one Checkbox with mark activity as milestone. Nothing gonna happen with this. The major problem is by default in this version of Windchill ProjectLink F000 we can start to make directly an EPP. First when we create a plan, it's a Classic. Kindly help.

Will be highly appreciated.

Thanks
