Not able to check-in

Mar 9, 2008 at 3:21 AM

I've never used a version control software before and I am completely confused as to how to use this CPC.exe. Here's my situation

1) I am the author of the project "ExportToExcel"
2) I recently released a newer version. I'd like to post the revised source code.
3) But I computer crashed recently and I had to take a copy from my backup and apply the new changes.
4) How do I now checkin the new version? Please indicate the "Exact" steps from start to finish

Thank you
