SWF To FLA Conversion

Hi,
I need something from you guys and gals. I was realy happy to find a long lost treasure. I found SWF file of a project we did before summer. My HDD got stolen that time, I lost all source files that day and we gave all copys of SWFs to the client. Today I found a directory with almost finished SWF and early FLA of that thing. I dont have any software to recover the FLA and trial versions lack this possibility. So could someone be so kind and do this for me, if you own such software? It can be found HERE (its about 5 MB). Thanks a lot =)
