Hmm, I had 19 transactions (2$ each) yesterday now listed as Adjustment (Invalid Transaction). 
As WarrenPrice noted, it brings decent chaos in that earnings page... 
I just sent them email...

You are not alone... My Fotolia account was even blocked for few weeks due to number of problematic sales right around 2-22-2009.

Hello,
it took a LOT of emailing, but my account is working again. They are still investigating situation, but I really believe in happy end now. 

Charles79:  I would suggest to contact more people from Fotolia management. There is section Management on Fotolia Blog, where You can find email addresses. I wasn't trying to contact them on the phone, because I am more confident in written communication in English.

Thanks for replies!

Still waiting for some factual answer from Fotolia. I believe, that Fotolia will be able to find out, that I have nothing to do with those problematic (?) transactions.

Hello,
I had good experiences with microstocks until now. Fotolia blocked my account almost two weeks ago. They did not write me any explanation. I believe it was because of someone´s stolen credit card. Because two days before my account was closed, there were abnormally high sales. After that some 50 UDS has been erased from my account (Credits have been refused). I understad this can happen. I contacted support and received contact on Mr. Chad Bridwell. But after week of writing e-mails Iam still receive no explanation. My account is blocked and Iam starting to be very angry on Fotolia  Please, do you have any experience with this problem? Can you please give me some advice. Your help is appreciated.
Thank you, Klara
