Uninstall real player!! Mine was doing the same thing. To uninstall, go to Control Panel then Add/Remove Programs, find Real Player in the list and uninstall.
I have an hp pavillion laptop. When my children try to log into the Webkinz member website, the screen goes blank. Technical support on the website suggests that I get get the latest Adobe Flash (which I have done) and Internet Explorer 7 (which I am running).
We have no problems accessing the site from my desktop Compaq w8000.
Does anyone have any suggestions?
