Greetings ALL,
 
I'm in need of helpfull insight and/or suggestions...Ouch
I'm currently running LLD 2004 and I had several sessions open
when all of a sudden things froze up, then I couldn't get the OPEN
command to work. I've run into these glitches before, so I pulled the
classic "IT" first answer to everything
I TURNed IT OFF, and THEN BACK ON.
Now when I start an Autocad session up this i what I'm getting....
 
AutoCAD menu utilities loaded.
Loading AecBase40...
Loading AecUiBase40...
Loading AecCivilBase...
Loading AecDraft...
Loading AecLS...
Loading AecGuiBase40...
Loading AecUtilities40...
Loading AecCivilApp...
Loading AecLayerManagerUI40...
Error opening PP message file!
Error opening ZQ message file!
Unable to load message files.
Initializing...; error: ADS request error
; error: syntax error
Angry
 
I followed the bouncing ball and tried replacing the following files
AecLayerManagerUI40.arx
AecLayerManagerUI40enu.dll
thinking they got coorupted, but no dice.
