[UDM problem] USER DEFINED MACHINE MODEL "TA" NOT ACCESSIBLE

edit

I created a UDM "AA", but I get an error as shown below twice.

BUS 1 [NAME] MC 1 USER DEFINED MACHINE MODEL "TA" NOT ACCESSIBLE BUS 1 [NAME] MC 1 USER DEFINED MACHINE MODEL "TA" NOT ACCESSIBLE

Do you know what is problem?

I also got an error during compilation like below, but the .dll was created.

Microsoft (R) Windows (R) Resource Compiler Version 10.0.10011.16384 Copyright (C) Microsoft Corporation. All rights reserved. Creating C:\Users\ex.pssenvmgr\YCKim_GFM.res C:\Users\ex.pssenvmgr\TA.rc(16) : fatal error RC1015: cannot open include file 'afxres.h'. Using codepage 949 as default

ERROR compiling resource file C:\Users\ex.pssenvmgr\TA.rc. Version will not be added to DLL.

Is this a problem?

DLL is loaded correctly, and if I initialize it without loading it, I get an error message like the one below.

BUS 1 [NAME] MC 1 USER DEFINED MACHINE MODEL "TA" NOT ACCESSIBLE BUS 1 [NAME] MC 1 USER DEFINED MACHINE MODEL "TA" NOT ACCESSIBLE BUS 1 [NAME] MC 1 USER DEFINED MACHINE MODEL "AA" NOT ACCESSIBLE

What's wrong?
