I keep getting this message "calculated CRC32 does not match the one found in SFV file" Help!

The file is corrupt & will be unshared because CRC32 does not match the 1 found in SFV. You need to find the correct file that matches sfv. This feature has been introduced since DC++ 0.688 - Files with invalid CRC-32, as per their SFV file, are no longer shared.

As I read on your previous post, here's the information link for CRC32 & SFV, since you have little knowledge in computers:
Cyclic Redundancy Check (CRC) http://en.wikipedia.org/wiki/CRC32
Simple File Verification (SFV) http://en.wikipedia.org/wiki/Simple_file_verification

Hope this information helps.

Make sure that either those files are not corrpted or the sfv files themselves are correct by a software which is capable of sfv check, such as Total Commander, etc..
Try to (re)create some sfv's and check if the files accepted by DC++ then.

eMTee suggests this newly created FAQ article as an answer to your question:
FAQ #256: “I can't add certain files to my share and I keep getting this message “Calculated CRC32 does not match the one found in SFV file”.".

As others have said here this is what I see >>>>not shared; calculated CRC32 does not match the one found in SFV file..

 My files are not corrupt since all of them have been from DC++ a few years ago. I have no idea what to do. I have tons of music to share and no one's going to let me take anything if this is what they get when they try.
