Coworker's FLAs are lost, IT may not be able to restore

Need a decompiler recommendation. For 2 months about a year ago a former coworker’s Flash files were built in a totally inappropriate system tailored for print. Turns out that this square peg round hole idiocy has resulted in files sent to archive that IT may never be able to restore. A client has asked nicely if they can use the same FLAs that were created for them last year and we do want to accomodate. Before I use the co. credit card I am looking for decompiler recommendations.
