Even though your file names say .fastq it looks like your files may be compressed/gzipped. What do you get if you do file ERR770964_1.fastq and file ERR770964_2.fastq?

I asked you to provide output for the two commands above. Without that there is not much we can say.

If you are Linux user try zcat merged_file.fastq you can decompress via gunzip merged_file.fastq, then open it
