Extrusion not working in 9.9

[jbinion]

I downloaded the new version of Slic3r, and now nothing comes out of my extruder...lol. I found the the problem:

; generated by Slic3r 0.8.4 on 2013-03-31 at 21:03:50

; layer_height = 0.4
; perimeters = 3
; solid_layers = 3
; fill_density = 0.4
; nozzle_diameter = 0.5
; filament_diameter = 3
; extrusion_multiplier = 1
; perimeter_speed = 30
; infill_speed = 60
; travel_speed = 130
; scale = 1
; single wall width = 0.53mm

M104 P200 ; set temperature

M109 P200 ; wait for temperature to be reached
G90 ; use absolute coordinates
G21 ; set units to millimeters
G0 Z0.400 F7800.000
G0 X77.310 Y76.970
G0 F1800.000 A1.00000
G1 X77.740 Y76.560 F540.000 A1.01747

That underlined line seems to add 1 to the extrusion but in the newer version it defaults to 0 even though I am using the same configuration file:


G21 ; set units to millimeters
M104 P200 ; set temperature

M109 P200 ; wait for temperature to be reached
G90 ; use absolute coordinates
G0 Z0.400 F1800.000 A-1.00000
G0 X76.930 Y77.080 F7800.000
G0 F1800.000 A0.00000
G1 X77.080 Y76.930 F540.000 A0.00624

And the steps for the extruder are totally different! Help!!!!!
