I have a 16900A which recently became unusable. After boot, the "Instrument Details" shows that the only module installed is not working. The module's initialization status is "DLLs not locked after load, failing DLLs = 33". So it remains uninitialized and the LA software crashes when I run it. If I remove the module and boot the LA, the software indicates the instrument is in working order. I have used this instrument in the past, so I'm not sure why I see this error now. Any suggestions?
