ios5 - Unable to connect iPhone 3gs(iOS 5.0.1) with Instruments application

Question

When i am connecting my 3gs(iOS 5.0.1) device to Instruments i am getting this error message

" Failed to start Instruments daemon for 'iOS' on  iPhone 3GS (v5.0.1)' (The service is invalid.)

Please reconnect the device."

This message appears on instruments, when ever i re-connect the device. How can i do performance testing with this device.

Thanks.

I have no idea what is causing this - but i did find a solution that worked on both devices that caused instruments pop out this message - making them unusable. I simply started Xcode's Organizer, and after Organizer reading the devices' data - both worked with instruments flawlessly.
