Oh, sorry I did not realize you were asking your questions pertaining to "free" mode. Before I became a premium member with RG, I was NEVER able to download a single file in free mode. I believe you are going to encounter issues downloading in free mode regardless of a download manager, in fact it may be more difficult because of the wait time and/or captcha. I would suggest you pick a service and become a premium member, if you can swing the cost.
