I think you should email your problems to
customer.supportATbsplayer.com (Replace AT by @)
After purchase you will receive an email from
BSPlayer sales,
reading (i.a.):
You can download BSplayer Pro at ..... followed by a link to your log-in page.
and on the next two lines in the email there will be your
Username and
Password to be able to log in at the download page.
After log in you will see a page with a welcome text at the top right and also:
(Just click on [Get BSplayer PRO] to download.)
PS:
If you do not see the [Get BSPlayer PRO]-button, another suggestion I could give you is use "reply" on the email you received from BSPlayer sales (with their original email to you included in/attached to your reply-message) and mention your problem to them. (It appears that a few emails which they sent out were not entirely correct.)
The Registered User Name and Registration code(s) also mentioned in the email are to activate BSPlayer Pro once downloaded and installed.
