Hi my Flash FXP Trail is gone and now I can't FTP to xbox. does anybody know a way I can get Flash FXP working again without purchusing it like with a registration code. Thanks.

just pay for it, it is worth it. Stealing is just wrong and is not condoened on these forums.

Option 1: Buy the software since it doesn't cost that much and its worth it like pinoy1621 said.
Option 2: Find the correct Registry keys that log if you have installed FlashFXP before and your trial expired and delete them. (Backup registry before hand!!!!)
Option 4: Format your Hard Drive and reinstall Windows and FlashFXP and get 30 more days of usage. (Stupidest option...)
Option 4: Just get a crack from here or serial from here for the version of FlashFXP that you have.
Option 5: Get another FTP program like CuteFTP, 3DFTP, WSFTP, LeapFTP, SmartFTP, or just use Internet explorer this way: "ftp://user:password@IP Address:Port#" (ex. "ftp://xbox:xbox@192.168.1.101:21") (with out the quotes)

Hope that helped!
