LP-MSPM0C1104: Error: No GNU Arm compilers, supporting device 'MSPM0C1104', are currently installed!

Hello,

Since the MSPM0C1104 is quite new, it sounds like maybe you have an old version of the compiler installed that doesn't support it and requires an update.  

Can you try going to "Help -> Check for Updates..."  ?  

If that doesn't work, can you possibly try updating to the latest version of Theia?  It should come with the latest support files and compiler needed.  

Thanks,

JD
