getting error after rehosting

Hello friends,

I just rehosted a windchill 9.1 M040 envt.

After rehosting when I started the application and tried to open the contexts, I get the following error...

Failed to get default type definition"wt.epm.EPMDocument|com.xxxxx.DefaultEPMDocument". EPM default type definitions not configured properly. Please contact administrator.

Through existing TPI I found that if we update and checkin the soft type, it can be fixed...But when I try to do this in Type and attribute manager, I get the same error as a pop-up...

Thanks
