This is not my crack I am not working on "CorePacks" crack. All rights to him.
I am not responsible if you catch a virus or trojan, I did not program the crack.

Is this file clean?
I can not assure you that his crack is fully clean, I took a look at the Sourcecode.
There is some suspicious code which looks like an IP logger -> screenshot: https://i.ibb.co/d6YhL67/iplogger.png

And additional code for a mail service so it sends e-mails to him with hidden content which could be maybe your account data.

If you don't trust me that it is actually his sourcecode, you can download his sourcecode on my website.
Just click on "Download Sourcecode" and see for yourself. With autoit installed you can also just run this sourcecode.
