I am using the latest RPU with the latest challan file downloaded from eportal and it says :
T-FV-3175 Either you are using old FVU version or old challan file (i.e. .csi file), please use the latest FVU version and challan file available at www.tin-nsdl.com and validate the file. |
Can anyone explain how to fix this? I really appreciate any help you can provide.
