What do I do when membership is not upgraded automatically after payment?

The administrator will upgrade your account as soon as possible.
Forgive if this is the rare case!

What do I do when I can't find what I am looking for?
Before logging in and paying for membership upgrades, you need to know that there are a lot of documents you can download or use online (which is what you see / hear when you are not a member). Please use the search feature when downloading as well as browsing the site to get the most results.
However, there are no available guarantees for all that you are looking for. So please consider carefully before making payment so you don’t have to complain later.
The following note should be emphasized: The above resources are classified into 3 functional groups:
1-Online (Use online); 2-Download (Downloadable) and 3-Projector (use online but with clean content, no stamp, no watermark)
Because these 3 functional subgroups are independent, it is impossible to guarantee the same data in all 3 groups at the same time. The update speed is different so the number will increase but not evenly.
If you still cannot find what you are looking for, please send an administrator support request, for instructions on how to search or update manually on a specific request.
