Payment module not completely seen in admin on the screen

1. Download and unzip a fresh copy of the master Zen Cart zip.

2. Compare your server's list of filenames with the ones from the original fileset, specifically for these folders:
-/includes/languages/english/modules/payment
-/includes/modules/payment

3. Delete any that aren't in the master set and which you haven't intentionally installed.

4. Re-upload all of the files in those folders from the master fileset, making sure all files load without any errors.

5. Re-apply the PayPal patch, making sure to put the right files in the right folders, as found in the patch zip. You may as well use the newest patch while you're at it.

Thanks ! Thanks !
I have done that. But I had also to remove the 2checkout module, that I do not use anyway. Why ? Mystery ! Everything OK now.

Excuse for ANOTHER QUESTION.
I have document dowload installed and functionning well. The problem is that it offers 2 mode of payment : paypal and check/moneyorder. I don't want the check possibility, only paypal/creditcard for the downloading. I didn't found the way to have only one possible mode of payment for downloads.
