WinXP gives error message on install of different gnutella downloads. pngu3266.dll is the file. This is on a friend's computer and I had her download the dll file but haven't heard how it turned out. Does anyone know if this will cause serious problems? I had her check prior to this and she had GUI related files; Java, Shockwave, etc... and they were on the HDD. I'm stumped. Thanks for the assistance!
