Argunet.exe error

When running Argunet.exe (v2.0 for Win32) I get the following error message:
"The e?u executable launcher was unable to locate its companion shared library."

Note that there was a block character preceding "e?u" which I
couldn't reproduce here. The ASCII codes for the word "e?u":
0C 00 65 00 D4 0D 75 00

Using a file system monitor, I couldn't detect any attempt to load
any file at all.

Using OllyDbg, I found where it called LoadLibraryExW and it passed a null
pointer. Another odd thing about that was it also indicated that the same
line was a call to "lstrcpynW".

00402EF3 PUSH 2
00402EF5 PUSH 0
00402EF7 CALL ARGUNET.004014C9
00402EFC PUSH EAX ; |String1
00402EFD CALL [DWORD DS:<&KERNEL32.LoadLibraryExW>] ; \lstrcpynW

I'm using a work-around now consisting of a .bat file with the line:
"java.exe -jar .\plugins\org.eclipse.equinox.launcher_1.2.0.v20110502.jar"
