Hello,
Because the license you purchased is not expired, which enables FREE hot fixes and new releases for 1 year, after correctly applying the licese to your application, there would be no any warning messages on converted PDF when you tried the dlls(Spire.Doc Pack(hot fix) Version:5.2.24) I provided, vice versa, so please check if the method to apply the license is correct.
And how is the demo we provided in the email going on your side?
Sorry that it is impossible to provide a license copy of the hot fix, you need to apply the license before performing any operations with our products.
BTW, the following guidance is how to apply the license.
