OpenFlows FLOOD Time Series and HDF Files not showing when running a simulation

Hi! I am currently working for my Capstone design project that involves the use of OpenFlows FLOODS for modelling. I followed the instructions from the youtube playlist for "OpenFlows FLOOD Tutorial" however I am experiencing a difficulty when it comes to the Time Series and output data. When I try to save my file, the software wasn't accepting the file, and when I run a simulation (the NodeTimeSeries file was accepted), it doesnt reflect on the Time Series data and HDF Files. I hope someone could help me out, the deadline was near too and I can't afford to fail. Thank you very much!
