Yes, maybe an help file should be of help to some users, but BSplayer was born as a sole man work (BST alone developped BSplayer untill v1.01) and he had to choose to write an help file while developping the software or put all his efforts in improving it (and BSplayer grown really fast especially in the pre v1 stage and it was almost impossible to follow all of its changes).
Then some FAQs started appearing (the first useful FAQ was the one that now is available on the homepage FAQ section), then BSPeter wrote his really really really useful FAQ for v0.86 and once v1 came out improved and rewrote it (and he is still improving it) to follow BSplayer changes and (noob and not so noob) users needs.
Plus BSplayer team is composed of really few members (3 or 4 I think) and they have a lot of work to deal with in improving the player etc.
Yes, the support lacks a bit, but they also had lots of problems with spamming posts and e-mails (and this is the first reason why some support requests were not accomplished by e-mail), especially after the choice to add WhenU Save adware to the player installation process..
Here on the forum we (BSplayer users like you) are trying to help each other to solve configuration problems and other little tune-ups, and also try to figure out which bugs BSplayer still has to help developpers to fix them and improve this great player.
I hope that the support system will be rearranged soon since paying customers deserve (and have paid for) a full support
