VMManagerException: Incorrect supplied InstancePath

Hello Gurus

I'm facing a problem with Diagnostics Setup (Introscope Agent Setup)

The Setup Wizard ran without problems but in the Introscope Agent setup I have this problem

This System (SAP Portal) was migrated from NW 7.0 to NW 7.3 and some paths were changed and before the migration the system had SMD running without problems

Some of you know what i should do? I'm using Solman 7.0 SP28

Thanks
