[pca] Problems with license validation

Hi,

Ok, no problem :)

> Well, it seems, sunsolve has problems:

Yes. Your debug output looks fine as far as pca is concerned, it follows 
SunSolve's redirection to the actual content nicely, but then it fails:

> HTTP request sent, awaiting response... 500 Internal Server Error
> 15:13:55 ERROR 500: Internal Server Error.
> 
> If I try patch 119254 I sometimes get "503 Service Unavailable" or "403 
> Forbidden" messages.

That's SunSolve in a bad mood once again. I have the same problem right 
now, and I had failed downloads in the last few days as well. It usually 
seems to work in the morning (MET), but has multiple outages of 
different duration during the day. The error message differs 
(500/503/403), and seems to be random.

So I'm afraid I can only advise you to try again later, or set pca's 
--dltries option to a very high value and leave it running.

Or sue Sun.

> Not all fail, but most of them. My account is connected to a contract.

pca's download functions are simple enough to assume that if it works 
(or has worked) once, it will always work. It's nearly always SunSolve's 
fault.
