Strange linking Error and HEX File

Hi!

My versions:

IDE-Version:
µVision V4.00a

Toolchain: RealView MDK-ARM Version: 3.20
Middleware: RL-ARM Real-Time Library Version V3.21
Toolchain Path: BIN31\
C Compiler: Armcc.Exe V3.1.0.919
Assembler: Armasm.Exe V3.1.0.919
Linker/Locator: ArmLink.Exe V3.1.0.919
Librarian: ArmAr.Exe V3.1.0.919
Hex Converter: FromElf.Exe V3.1.0.919
CPU DLL: SARM.DLL V3.20
Dialog DLL: DARMP.DLL V1.34
Target DLL: BIN\UL2ARM.DLL V1.37
Dialog DLL: TARMP.DLL V1.34

The linking error:
linking...
C:\Keil\ARM\RV31\LIB\armlib\c_t.l:SELECTION_SCRIPT(1229): error: L6278E: Missing expected ).
C:\Keil\ARM\RV31\LIB\armlib\h_t.l:SELECTION_SCRIPT(11): error: L6278E: Missing expected }.
".\Obj\Holli_Application.axf" - 2 Error(s), 0 Warning(s).

My question(s):
* Does anybody know what's the reason for this errors? Building of project was ok and the files c_t.l and h_t.l are ok, too. Last modification was installation of µVision V4.00a. The project was working bevor.

* If i install new MDK and rl-arm versions will the hex file still be the same? I actually use two applications with two hex files, one must always be the same (due to certification reasons) and is controlled via checksum.

Thanks for your help!
