Program not pulling data off oscilloscope

I cannot get my program to give me data back from a Tektronix TDS oscilloscope.

My commands are as follows:

g=instrfind('name',sprintf('GPIB0-%d',1));
fclose(g);
set(g,'outputbuffersize',1000000)
set(g,'inputbuffersize',1000000)
g.Timeout = 120;
fopen(g);
fprintf(g,sprintf(':data:start 1');
fprintf(g,sprintf(':data:stop %d',1000));

fprintf(g,':CURV?');
data=fscanf(g)

Which returns the follwing instead of data:

data = :CURVE #42000

Has anyone ever experienced this before or know a possible solution?
