Problems with IIS and Piwik (no replies)

Hello people.

Im using Piwik in Linux and Windows and I have a lot of problems running it on IIS.

The problems are always of the same style:

2013-05-08 12:51:16,450: [DEBUG] Error when connecting to Piwik: <urlopen error
None>
1000 lines parsed, 200 lines recorded, 8 records/sec (avg), 0 records/sec (curre
nt)
1000 lines parsed, 200 lines recorded, 8 records/sec (avg), 0 records/sec (curre
nt)
2013-05-08 12:51:18,490: [DEBUG] Error when connecting to Piwik: <urlopen error
None>
Fatal error: None
You can restart the import of "c:\u_ex130503.log" from the point it failed by sp
ecifying --skip=200 on the command line.


<urlopen error None>

I have tried with IIS 7.5 and 8. PHP 5.2, 5.3 and 5.4, little logs (rarely crashes) and medium or large logs (frecuently crashes), python 2.6 and python 2.7...always this problem. I include download and install piwik with IIS Wep Platform...the same happens.

Another thing is that if I process the logs in the linux system, redirecting them to the Windows system, the process fails too, but, if I process THE SAME LOG in the windows system to the Linux System (with Piwik installed) or ALL THE PROCESS in the Linux System, ALL GOES WELL and the <urlopen error None> NEVER HAPPENS.

I think that its an IIS+ PHP configuration, but I dont get better results. I attach the log to verify it, but in Linux System it is 100% processed without the error.

Any ideas?

Thanks a lot and sorry by my English.
