I fired up my upgraded Peformora 575 and launched Eudora. It has been running great for me. When Eudora launched, it gave me a error message that said it could not launch Eudora because CarbonLib was missing. I ran Tech Tools Pro and it found some problems, fixed them, but I get the same error message. Is this error message coming from Eudora? If I re install Eudora, will I loose all my past email or will it over write it? Thanks for the help. Jack in Portland Oregon
