CCS/TM4C1294NCPDT: Timer PWM Mode doesn´t load and start

Tool/software: Code Composer Studio

Hello

The first Problem is that TimerLoadSet() function is not loading any value into the timer. It´s always the default value of 65535. 

The second Problem is that the timer is not starting. The TnEN Bit of the GPTMCTL Register is set when enabling the timer but it´s not starting. 

Do you have any ideas how to fix that? Thank you! :)
