ITunes crashes when trying to log in to the Store... Help?

Question

I am using iTunes 11.4 on an iMac (OS X 10.6.8). Until yesterday everything worked fine, but now every time I log in to my account, iTunes freezes and crashes. I didn't do any updates and there doesn't seem to be a problem with the internet connection since it shows me that I have been logged in and I can browse the store while not logged in. My brother can log in to his account without any problem at all using my computer. Help? ):

Hello user526627 and all,
I also have installed apex 2.2 successfully. At least I've not found any errors and this is the tail of install.log:
Thank you for installing Oracle Application Express.
Oracle Application Express is installed in the FLOWS_020200 schema.
The structure of the link to the Application Express administration services is as follows:
http://host:port/pls/apex/apex_admin
The structure of the link to the Application Express development interface is as follows:

Interesting thing is that I am getting 404 when I use suggested http://host:port/pls/apex/apex_admin or http://host:port/pls/apex (I am using host name of the machine or ip address). However the http://host:port/pls/htmldb/ and http://host:port/pls/htmldb/apex_admin works (at least, I am getting a page without images). In addition, when I provide user name and password on the http://host:port/pls/htmldb/apex_admin page and click on 'Login' nothing happens... :(
This is a clean install. I've also used a HTMLDB 2.0 install from companion cd (Oracle10g R2 for Windows) - this had worked ok, however it did stop working when I istalled apex 2.2 on top of it. I've dropped flow-schemas and tablespaces I've created for apex 2.2 install and started the install over again. However, still no luck. Here is the command I am using to start apex 2.2 installation:
@apexins ********** htmldb_data htmldb_files htmldb_temp /i/ none
I have installed oracle http server in a standalone home, the http server works.
Thank you for your time,
Daniel
