Clickbank sales dead

here's the deal. I have a website that sends a fairly stable amount of traffic to an offer.
I started to promote it with an old account - no sales for a few weeks.
Created a new account - boom... sales start to jump, every 2-3 days a sale.
Then the sales stopped again.
I created a new account... sales started... then again completely stopped.
Naturally created a new account...good sales for a while. Had a peak in traffic and got some nice cash. Right now I am waiting for the check.
But few weeks ago the sales stopped again. I looked at my stats - there was a peak in traffic again but no sales. I should be getting at least a sale in every 200-300 hops but nothing.
That's just fcked up. If I keep creating new accounts like this I will have to leave a lot of money on the table. Cus i have like 130 dollars in one of the old accs but I can't get the money because it doesn't meet their minimum requirements or whatever. What do you suggest I do? completely move on to another company? Isn't there a way to call them or something?
Maybe some of you had this problem and fixed it somehow?
Thanks for the answers

I dont know.....i have only ever had the one account and while i have had a few days of zero sales last year, it has been pretty constant. i think you should just stick to the one account and do deeper analysis to see when the sales happen, time of day, day of the week, time of the month etc and see if there is a trend. Also note if you are getting traffic organically then it may also depend on your Google rankings for that period.

you should get traffic from niche will help you rank lead
if your traffic didn't get from niche will hard to sell nowaday

Well, I didn't create any new account (is it really that simple, btw? Can you just create one from scratch using the same info?), but I have to say that in the past I had a week with zero sales despite the traffic was consistent, so I mailed the support and they gave me the usual default answer, but the day after the sales started to pour again...

Coincidence? I don't know, but unfortunately I don't think that's much we can do about this anyway...
