I just tried paying my affiliates via the masspay.txt file and it doesn't work. I always get the following error when entering it in Paypal:
This mass payment cannot be processed because there is an error in the file format. Please make sure that the file is tab-delimited and that each entry has a corresponding email address, payment amount, and currency code. In addition, please specify only one type of currency per Mass Payment file. The error occurred on line 1, and the text of that line is: "content of line1"
Nothing of what this error says appears to be wrong in the file and I already tried many different variations with no success.
