Hi All

I just wanted some help form anyone i am not sure the balance of my private key but that is not the main issue....

The main issues are as follows
1) i have a private key which begins with K and is 49 Characters long base58
2) i have a private key which begins with K and is 54 Characters long base58

I am not sure how to resolve this and kind the actual private key i have even wrote BTC address down wrong...

Could someone kindly help as i could use the BTC's right now!!!!!
PS: If i use the the script on here and use this in github https://pastebin.com/S8WARrRn? will it work or do i have to use it on pastebin to run the script ?
Many Thanks
