Hi shorla and welcome to 4WM
Sorry to hear of your problem, it is one of those niggles that can drive you nuts! Do your store your ringtones on the memory card or do you mean the default Windows ringtones?
I would try a power off and back on and see if that does the trick.
Hold the power button in until you get an on screen message confirming your action and turn the device off, give it 10 seconds and power it back on. Let us know how you get on.
