Combo,
save this file under another name, then delete the top line, ##1 0 (1 49 1 6 0)##, and try the 'new' file . Your data looks ok, should work, my guess is something may have happened the first time it tried to load, now it's 'stuck'.
The other possibility is that your file is corrupted and the prog can't read it, take a quick look down the whole file to see if a nr is missing or out of place, etc. If not obvious, you will need a new file rather than trying to find the error in all that data.
Btw which version are you running now?
