I am very sorry to hear that you apparently are the victim of an attack against your files using AxCrypt.
However, please understand that AxCrypt is just a tool that is used by millions of legitimate users for good purposes. I am very sad that someone would choose AxCrypt as the tool to perform such attacks.
Unfortunately in this case, AxCrypt is based on strong encryption, and it is generally not possible to crack the encryption.
What you must do is contact your local police.
