Errors: "Invalid object DNA" and "Root element is missing" in one crash.

[KurD]

Unfortunately, I mistakenly clicked the "Solved" button in the topic  https://communities.sas.com/t5/SAS-Enterprise-Guide/Errors-quot-Invalid-object-DNA-quot-and-quot-Roo..., but problem is actual.

The problem was described like this: 

One of my users have 2 errors: "Invalid object DNA" and "Root element is missing" in one.

Machine: Windows 8, Sas EG version 7.13 HF5 (7.100.3.5486)

I read thread https://communities.sas.com/t5/SAS-Enterprise-Guide/Invalid-object-DNA/m-p/363310

She don't have two EG sessions in parallel which both updated the file and then got a garbled content back

Also I made profile changes, as sade in https://support.sas.com/kb/58/672.html - no change.

I thought: that file(project) is damaged - but it propertly on the machine of other user. They use the same file from the same sharred sourse.

We tried to reinstall EG and  make this algoritm: -Close any open instances of SAS or SAS Enterprise Guide.
-Open a Windows Explorer window and navigate to C:\Users\your-user-ID\AppData\Roaming\.
-Locate the folder titled SAS and rename it SAS_old.
-Restart SAS Enterprise Guide (the error should no longer occur).
-Close SAS Enterprise Guide.
-Again navigate to C:\Users\your-user-ID\AppData\Roaming\ and open the SAS_old folder.
-Copy the MetadataServerProfiles directory into the new C:\Users\your-user-ID\AppData\Roaming\SAS directory (overwrite the new MetadataServerProfiles directory). This step ensures that the existing connection information is still available.

It didn't helped. Today user came back with the same error: "Invalid object DNA" and "Root element is missing".

We will try to remove %appdata%\SAS\EnterpriseGuide\7.1 at all and recreate connection profile from the begining.

When does this problem occur? When opening or saving an EG project? Does it happen to a particular EG project - is it only one project affected or all?

Check if your EG 7.13 has these hot fixes applied: http://ftp.sas.com/techsup/download/hotfix/HF2/A3V_win.html

Problem occures during work of project. According to user - error affectes only on one project. The same project on other machine is working propertly. I will try to install fix today

It seems - deleting folder C:\Users\USER\AppData\Roaming\SAS\EnterpriseGuide\7.1\ and re-creation of the connection profile to SAS fixed the problem
