"Error in file...Unexpected end of file" for categorical soil variable in MaxEnt

[Georgia Kielbaska]

Hi  guys, 

I'm attempting to create a species distribution model with continuous worldclim variables and one categorical variable being soil sourced from this link https://www.asris.csiro.au/themes/Atlas.html . However I keep getting a "unexpected end of file" error every time. Below are images of the ascii files that show that the resolution, no data value and cell size are exactly the same between soil and one of the bio variables. 

As the soil data was downloaded as a shape file I had to convert it from a polygon to raster and then raster to ascii at the spatial resolution I wanted. This meant i jumped between the "conversion tools" toolbox and the SDM toolbox v2.4 and wondering if an issue has come about there. Also, when converting the raster file (I believe it is in ESRI grids as it didn't save as a tif file) to an ascii file I got the below error however still received an ascii file in the output folder after that process? 

I've been trying to figure out this issue for about a month now and I've looked at past error conversions here. If anyone could provide any recommendations or explanations that would be great and preferably not in R or QGIS but in ArcMap!! 

Thanks, 

Georgia
