Can't log into Oracle Application Manager

Question

I just finished installing Oracle Apps 11.5.9 on Windows 2K Advanced Server with the Vision database. The install went without any problems. However, when I tried to log into OAM I get an Internel Server Error. The error.log file for Apache has the following error:
[error] [client 192.168.0.16] Filename is not valid: h:/oracle/prodcomn/portal/prod_ora-apps/redirecturl$url=$|servlets$|weboam$|oam$|oamapps$$target$=prod
In the jserv log file (mod_jserv)
(ERROR) ajp12: Servlet Error: <blockquote><b><br>java.lang.NullPointerException

Any ideas on this problem. Any help would be greatly appreciated.

Thanks for your reply Mylenium.
OK, now I can log into my Adobe (website) account and see my purchases, serial numbers, etc. .... AND ..... I am now able to log into my Applications Manager!!
I did not do anything different from the other past few days; didn't load or download any software, nothing. Strange, but I'm glad it's back to normal now.
Figures; when I go and seek out assistance ... it fixes itself.
Thanks again ... and I hope this does not re-occur!!
