Cannot upload code because firmware update failed

Hi,

I have just got the Crowbits Inventor Kit delivered and, following the instructions, I connected the MicroBits controller to the PC.

I also installed and started Letscode (V1.1.0 RC3.4), added Crowbits-MicroBit module, and it connected fine.

The driver was recognized automatically, but I installed the driver again from the menu. According to the manual I also selected the Install Firmware menu item because I was connecting it the first time. When it was finished, it said it was successful.

Now, when I try to upload a simple code to display some text onto the controller, I always get the following error message from Letscode exactly as written here: "Install Firmware Fail, Try Again Please!".

In the log output window I see the following messages:

- - - - - - - - - - - - - - - - - - - - - - - - - -

What could be the reason? Didn't I get the latest software for download?
