If programming was successful in the Quartus Programmer (instead of doing the programming from the JTAG Configuration section of the Signal Tap window), Signal Tap sometimes will still have this message.  Just try clicking the start analysis button as usual to see if it still works.  If it doesn't, you may have made a change in your Signal Tap file that requires a recompilation, so the Signal Tap file doesn't match the Signal Tap configuration programmed into the device.

Does the suggestion from sstrell works for you? Do you need further help on this case?
