Am I 'OP'?

Yes. You are the Original Poster.

I don't think I can use this solution, because I already have build 822...

It seems that from ikegami's investigation that the entrypoint that cannot be loaded is Perl_newXS_flags which you should see mentioned in a pop-up dialog when the load fails (and should have mentioned in your post). The problem appears to be that this entrypoint required bu Class::MOP is not exported by the perl58.dll that is built by AS822.

Despite what ikegami said in Re^2: Class::MOP and MOP.dll, it seems that he got success using build 824. You should upgrade and try again. I know of no other solution.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
