Connected jumper cables wrong - immobiliser fuse keeps blowing

Hello
I (very) carelessly connected jump leads to the battery of a 2009 Clio the wrong way round.
Immobiliser fuse now repeatedly blows when I try to start the car.
Any help would be much appreciated.
 
1st what kind of Clio and what was the problem that you had to jumpstart.

I'm not aware of any kind of immobilizer fuse has the battery been changed does anything work electrically on the care and does the fuse blow when you try to turn the key or push the start button.
 
Thank you for reply
Its a Clio Dynamique 16v 1.2 litre
Lights had been left on so battery was flat.
Lights, radio, etc work with booster pack on battery.
Immobiliser fuse (in compartment below steering wheel) blows when i turn the key.
