Blank download page problem (htaccess added )

Blank download page problem.

I created a leval 0 with 99999999 download limit and uploaded into /wp-content/plugins/s2member-files
2 download test files (one zipped and one .pdf)

Once logged in as admin, i go into login-welcome-page/pdf-training/ section and click on the download links
wp-content/plugins/?s2member_file_download=mygreatfiletodownload.zip
and/or
wp-content/plugins/?s2member_file_download=mygreatfiletodownload.pdf

but i get a blank page ?
Oh i forgot, i do get the prompt saying that i got 0 number of downloads made in the past 30 days and that i’m unlimited (no worries)
After that it’s a blank page

Got my root .htaccess file setup

Host said that everything is alright on their end (after multiple checks)

What could be the problem ? I am very interested into buying this product ! It’s the only thing missing.

Let me know
Thanks
