MS Project with error TF82039

Question

I've already searched for this case but I cannot find any solution to solve it.

currently, I use MS Project 2010, connect to TFS 2010. Yesterday, It still connected successfully. But today, I have the error: "TF82039: Team Foundation was unable to modify the project plan."

Here are my steps to connect to TFS:

1. Create new 1 blank Project.

2. At team tab, click "Choose team project"

3. Choose 1 team project.

4. Click Connect -> appear 1 popup with above error message.

Please help me to solve this error.

Thank a lot.
