Under the conditions of the Free License agreement, you have access to support through this forum only. As it is a user supported forum, it may be that there is nobody able to assist you at the time you post your question.
I try to offer what I can in-between doing other things, usually during European working hours. There are some others from the US who will also offer assistance during their normal work day. So just hang in there if you do not get an immediate reply.
If you require a higher level of support, eM Client offers VIP Support, but you will need to purchase a Pro License to qualify.
