Hello, yes, this is not a valid SWF file, it does not contain standard SWF signature. .swf extension does not mean it is flash file, the decompiler must understand the file contents. This might be a file which is encrypted by some sort of loader. Without loader, it's just binary data we cannot understand. I am afraid we cannot help you with this task.
