You may receive the following error when trying to create a project on Project Server 2010 PWA:

This error as described in MSDN Project Server Error Codes here, comes from the invalid number of digits after decimal in Currency Format.

 

[ProjectOptCurrencyDigitsInvalid = 1037                      

The optional currency digits are not valid.]

 

The solution simply as the following:

1. Open Control Panel
2. Open Region and Language
3. Click Additional Settings
4. Click Currency tab
5. Change the No. of digits after decimal to any value below 3
6. Restart your server
7. Now go back to PWA and try to create a project, it should work

 

I hope that helped
