you have to run SSPL.exe from the file explorer. It has to be run from the PHONE memory, NOT the sd card.
Try a hard reset, both soft keys and reset with stylus. Hold all buttons until it asks if you wish to reset to factory (or something like that, you get the idea). Push "r" on slideout keyboard then "space"key. you now have to go through the alignment and everything again.
Even if you use this method, make sure you install Hard SPL V7. It is safer than anything else. You should also have checked what radio rom you were using as it has now been downgraded to 1.116.x.x, this may cause you some trouble later too.
Use the sd card method to fix this as it appears safer than using the pc. Just make sure you have got Hard SPL installed and have a charged battery. DON'T just think you can put it on the charger while flashing AS IT DOESN'T CHARGE...
