I can´t see the Guitar rig 5 Plug-in properties menu in the VST

Hello to everybody ,
Please , can anybody help me in this situation ?
 
I have a problem with Guitar Rig 5 and Sonar 7 , and the problem is, When I open a Project in Sonar 7  I can´t see the Guitar rig Plug-in Properties menu window in the VST, and also in the Synth rack ,(the menu for saving and loading presets and banks  and the "PROPERTIES"/Enable as Plug-in, Configure as Synth , etc...) But if I create a new project, I can see the VST properties menu window , and everything is ok .
The only way to “solve” this is to delete the Guitar Rig in Synth Rack and reinsert the Guitar Rig and the Preset in each Project.But I need another solution, because I have many projects.
But I have another Hdd, with OS and software almost identical, where I export the Guitar Rig presets and everything works without problems.
(All projects were created in sonar 7, so it should not be a problem of incompatibility)I think??!!
MY OS is Win XP sp2 x86, and it is a fresh install(I have to format the HDD)
 
Please help me .
 Thanks for all
