Product Export Issue?

something has happened to product export.

Can someone please explain step by step product export?

we are getting this error on the product export page.

Error[color=#B94A48]No fields selected for export[/color]

all the fields are selected and says active, selected??? where do we select them?? where it says active, means selected?? or do we have to go to all the products one by one and fill in all the details where the features are (google export) ???

that will take ages to fill in. i liked the old way where we could select all the products we want, change the file name to: products.xls and do all the editing on excel and upload.

why cant we do the same with this new version?

i see people are exporting the products but straight from SQL or with another addons.

can someone please explain how this export addon works?
