Assertion failed error

chiragpr hi, did you use AVEVA Global or any AVEVA net application ? 

The bad token might have a relation with this :

Can you tell us which version do you use ? Maybe something missing, did you try to reinstall it ?

thank you @ yann gueguen for replying,

yes i already reinstalled and I'm using e3d 2.1.0.25 version. 

Can you explain your step to this error ? Did this error is recently or did you do something special ?

Did you have this error for any computer ?

while opening the "Support" Module in design, this is recently error I'm facing.

Hi chiragpr 

I am also getting exactly same error while switching to "SUPPORTS" module.

Did you find the solution to this problem.
