Persistant Launcher Script Error

Hi everyone,

since the last major update I got occasionally Script Errors when starting the launcher.
The usual tip to delete the Browser cache and Temporary Internet Files from Internet Explorer didn't work, as well as changing the settings in the FFXIV_BOOT-file.
Also tried to run the program in Administrator-mode...unfortunately unsuccessful.

Though the script error changed since I've updated Java last night. Now it's blackscreen with only the language selection box accessible. I couldn't access the Final Fantasy Webpage: http://eu.finalfantasyxiv.com/ either. Even if I set exceptions for Firewall and Anti-Virus suite, it wouldn't run correctly.

Had this problem for a while now, and could fix it by clean the cache with CCleaner, but now its persistant :(

Anybody else get this problem or is there an official solution?

Thanks a lot for your help^^
