Trying out TI LM4F120XL Launchpad: processor does not support Thumb mode

Hello!

I used to work with my LM4F120XL Launchpad on the previous ( v2.3.X) versions of CrossWorks for ARM with Stellarisware libraries and CTL tasking libraries. It was tricky to setup correctly at first, but I figured it out. 

Now I upgraded and evaluated for 30 days for the latest release of the IDE, set up my older project, but I can not debug, and program my launchpad at all, because I always get the following assembler messages:

"Assembling LM3S_Startup.s

Assambler messages:

selected processor does not support Thumb mode 'vmrs r0,fpscr'

selected processor does not support Thumb mode 'vmsr fpscr,r0'   "

I tried to set the preprocessor definitions, added the followings:

gcc
NESTED_INTERRUPTS
CTL_TASKING
USE_PROCESS_STACK
STARTUP_FROM_RESET
PART_LM4F120H5QR

Also I tried to set the correct User Include Directories:

$(PackagesDir)/libraries/libctl/include
$(TargetsDir)/LM3S/CMSIS
$(TargetsDir)/CMSIS_3/CMSIS/Include
$(STELLARISWARE)/

The processor-related project properties look like this:

Target processor: LM4F120H5QR

ARM architecture: v7EM

ARM core type: Cortex-M4

ARM debug interface: ADIv5

ARM FPU type: FPv4-SP-D16

I installed the latest CMSIS package, Stellaris CPU support package and Stellarisware updates for CrossWorks for ARM package, EK-LM4F120XL board support package, Cortex_M support package, ARM CPU support package, even the TIVA CPU support package for trying.

I also tried to create a new project in the new IDE, because maybe it is not backward compatible or something like this, but the new solution worked the same, like any other. Then I tried to build a Sample project from the EK-LM4F120XL board support package, but it was the same.

When I need to rebuild a library (like the Stellarisware) I don't have this problem, only when it is LM4F-related of course.

With these project properties on the earlier releases of the IDE, it worked flawlessly. But I don't have a license any more.

By the way, I run it from Windows 8.1 x64 but I don't think it's related.

I really don't know what to do now.

Help me please
