Need help creating FLA out of SWF

[COLOR=#323333][FONT=Helvetica Neue]1) I no longer have the .FLA[/FONT][/COLOR]
[COLOR=#323333][FONT=Helvetica Neue]2) I plan to convert my .SWF to HTML 5 (eventually)[/FONT][/COLOR]
[COLOR=#323333][FONT=Helvetica Neue]3) Used a decompiler (trillix), but it was buggy–it corrupted the .SWF[/FONT][/COLOR]
[COLOR=#323333][FONT=Helvetica Neue]4) Need to retain most or all script, etc. from the .SWF to recreate an .FLA[/FONT][/COLOR]
[COLOR=#323333][FONT=Helvetica Neue]5) Is it possible?[/FONT][/COLOR]

[COLOR=#323333][FONT=Helvetica Neue]I appreciate any pro / guru advice–it’s been pretty hard to come by…[/FONT][/COLOR]
