iar embedded workbench returning mad errors

Hi

i have just installed iar embedded workbench (for ARM) on my pc, and have registered for an evaluation license. i have exported the mbed blinky project from the ARM MBED online IDE, (with the iar embedded option), and have opened the project file in iar. When i try to build or debug however (with an ARM MBED LPC1768 connected i get the following errors (also see screenshot for these))

"Error[Ta148]: Intrinsic function "nounwind iar_builtin_DSB" is not available in this architecture C:\Users\Catriona\Downloads\mbed_blinky_iar_lpc1768\mbed_blinky\mbed\TARGET_LPC1768\core_cm3.h 1537

Error while running C/C++ Compiler

Total number of errors: 4

Total number of warnings: 0 "

I was following the instructions at this link: https://os.mbed.com/handbook/Exporting-to-IAR-Embedded-Workbench Exporting to IAR Embedded Workbench - Handbook | Mbed Support. Please note, changing the compiler toolchain introduces many degrees of freedom in the system; these differences include the translation of C/C++ code to assembly code, the link time optimizations, differences because of the implementations of the C standard libraries, and differences based on compile and link options. os.mbed.com

I have no idea what to do next or how to fix this, help much appreciated

I have been installing all this on an HP pavilion laptop with a windows 10 64 bit OS.

I have posted my question here as have already sent an email to mbed technical support one week ago, and have still had NO response.
