The important part of the message seems to be "LoadEMUShareMemDll::Load() failed". I am not a seasoned Win32 developer, but my experiece with C++ leads me to believe this is a failure to load EMUShareMem.dll into memory. It seems to me that this library is loaded first when the items table is opened.
If my memory serves me correctly, the EMUShareMem.dll code was modified to perform some sort of caching with version 0.4.3. Also, it seems that this error has been reported primarilly by Win9X users whereas Win2K/XP users have reported their 0.4.3 servers behave properly.
I thought I'd download the source and take a look, but this may be better reviewed by more experienced developers. Please let me know if I am mistaken at any point so I'm not barking up the wrong tree.
Thanks.
