I have one thought - Rykk uses the location c:/UF/..... to store his uprs. The default location for UF3 to store parameters is in your "My Documents/Ultra Fractal 3/Parameters" folder. When you browse for UPRs, that's where UF will look unless you've told it otherwise. The reason UF3 stores formulas, gradients, parameters, etc. in the My Documents folder is so that if you ever have to reinstall, your files will be preserved:)
