Cant import company details

I cannot import company details using the file.
I have managed do this once but now still showing an error.
I have tried many other options and nothing works!

At the time of importing company.csv ,in that only enter mandatory fields
i.e Company, Abbr, Default Currency ,Country and import file

i did this ans still does not work

Under Mandatory fields is also Country

Are you keeping existing companies also in csv? or added only new those are not exist in application

only new which are not exist in application

Please check this csv

Try to upload,check whether same error displaying.

Its working now. thanks!!
