I think these Shockwave errors are caused by the server side and there is little we can do to solve them. (basically it is a bug that we are powerless to avoid)

I am basing this on my experiences from yesterday,
I have 4 acconts at BFAHP
1 account was acting strange and I played the other three issue free.
Latter I loged in and the strange account was working again.
I then had to let that game timeout.
after that it started giving me shockwave errors
so I checked my other accounts and one other was also giving errors but the other two were working well.
I was able to log into the accounts that were giving the shockwave errors a few hours latter.

Hope this helps someone.
