Anyone else not getting any sales showing up under the "Summary of images sold" or "Balance of account" areas?

Mine looks like this...

Balance brought forward:    $NaN    
Total sales:    $NaN
Commission / charges:    $NaN
Total payments to you:    $NaN
Balance carried forward:    $NaN
Cleared balance:    $NaN
Next payment date:    10 May 2012    

And I am unable to change the statement period, it just seems stuck on may 10.

On a positive note though, happy to say I'm seeing more Alamy sales in the last few months!

yes, same for me.

I seem to be OK I've noticed customer activity statistics haven't been updated since the 7th.  It's 3:20am London time so I'm curious what will have been updated by the time I wake up in 9 hours.

Lately it seems to me the site is getting progressively slower.

I'm not exactly sure what error you are reporting - my stats page seems fine and has a nice sale from the 8th.

All back to normal again now. Wish IS and others fixed bugs like that so quickly...
