SQL Assistant : System.ArgumentOutOfRangeException

Hi Guys,


I am facing a problem with my Teradata SQL Assistant It is throwing below error whenever I am trying to open it. I had re-installed it also but facing the same problem. Need help how to resolve it.


Just after the status of "Loading Database Explorer Tree" the pop up is coming as shown below. 



SQLAError.txt File is having the below log.

SQLA Version:

And if I click on OK on the pop up the next screen is coming as shown below.

Re: SQL Assistant : System.ArgumentOutOfRangeException

SQL Assistant is quite old and is an initial release with no maintenance fixes applied. I would consider upgrading.


But to answer your question, this can sometimes be caused by a corrupted .config file (in the same folder where you found SQLAError.Txt file).

Based on the traceback, you can try renaming the customized Toolbars.config (which will restore the defaults).
