Following a previous issue discussed --> Cross section profile distance not providing accurate distances?

It was highlighted that 1. My CRS layer projections were different to one another. this was a likely reason as to why my 'x-axis' (which was measured in degrees) distance was wrong compared to my 'y axis' (Which was measured in Meters).

To correct this error it was suggested to download the data using a 'DTM ASCII grid version'.

I downloaded the zipped file and extracted the data. Once uploaded to QGIS V 3.4 it provided a layer expressing contours.

I then saved the layer and converted the CRS from EPSG27700 - OSGB 1936 to EPSG:4326 - WGS84.

I then converted the contours (line data to Nodes), and from there I used the 'SAGA Triangulation tool'(And selected the 'Attribute which contains the heights of the contours) to try change the ASCII gird to a DEM RASTER file so that I could use the 'Profile tool' to get a cross section, where hopefully the 'X & Y axis are shown in Meters'.

However the error message --> The follwoing layers were not correctly generated. <ul><li>C:/Users/louis.gorringe/AppData/Local/Te,p/processing_14ed7d5b37fa420e9e4bb476694e1bd5/9c08ac2438404d9a006a9363ef6f329/TARGET_OUT_GRID.sdat</li></ul>You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm

Does anyone know how to fix this, or an alternative solution?
