Upload maximum not refreshing

My upload max (25) has not refreshed for this week.  Does the iStock week not start not Sunday or at least Monday?  I have files pending from the previous max upload.  Could this be holding things up?  Thanks for your help.

Well Your max uploads are 25 per week.. It means not nescessary from monday to sunday.. Let's say You upload 5 tracks on wednesday.. Ir means tere are 20 left.. Then You don't upload anything else, so there is still left 20 uploads.. When next wednesday comes, You are able to upload 25 tracks again.. I hope i explained that clearly

So, since I reached my max upload last Friday, I should, in theory, be allowed to upload starting this Friday, correct?

If You uploaded all 25 tracks on friday, then YES.
If You uploaded 2 tracks on wednesday, 3 tracks on thursday, and 20 tracks on friday, then this wednesday You will be able to upload 2 tracks, then thursday you'll be able to upload 5 tracks, and friday again all 25.. Do You get the system now?
