Errors Upon Launching Debug Mode in Dexterity

Hello:

I was successful in my own laptop's test environment with creating and testing Dexterity code in GP 2013 R2.

In the company's test environment, I have been trying to test this same code.

But, upon hitting the "Debug" menu selection in order to enter test mode, I get the following errors:

Unhandled script exception:

Could not load external 'DexlsODBCsqlDriver@GPDWIN32.dll'

EXCEPTION CLASS SCRIPT MEMORY.

When I click on "Debug", I get the following:

'Login_WIN_PRE on form Login'

'FilterDataSources of form Login'

Then, the "welcome to GP" screen came up.  But, nothing shows when I hit the drop-down list for "Server".

Any ideas?

Thanks!

John
