So I believe I made a terrible mistake. After I used the walletgenerator to generate a paper wallet, I printed it to a pdf file and saved it. I used the public address to mine and to receive my coins. Today when i opened the pdf file and turned out the printing is not full. That is, part of the private key is missing...
Does this mean I can never use the coins in the public address? Is there any way to recover? TIA!!!
Always verify the private key is safe outside your PC before proceeding. Take a photo of your screen, paste it in a word doc and zip it with a password and email it to an address you don't use for exchanges or whatever. I've learned some hard lessons too.
