Illustrator won't start

Question

I have for the last three weeks not been able to properly start Illustrator. It gives me the error message [PARM] and the times the program actually manage to open, all the toolbars are replaced with question marks. I searched for it, and it seems like it's because I have changed the language on my computer to a different one from the language that Illustrator use. It made sense to me since I've fairly recentely changed my (Mac) computer
settings from Japanese to Swedish(even though I thought it was a little weird that 1; I've been able to use it for a while with the new settings, and 2; I still to this day have no problem using Photoshop).
Anyway, I started searching around for a solution and found a recommendation to use a program called "Language Switcher" which enables you to freely choose which language you want to open the program in. By using this I manage to open the program and the text had returned. But now the program told me that I'm missing an input; PDF Format aip. I could still open a new file but all the tools had disappeared.
I've tried to update both the computer and the program, as well as un-install and re-install it, thinking I might have messed something up trying to fix the language problem, but it didn't work. And now for some reason, with or without the "Language Switcher", I'm not even able to open the program at all anymore. I also checked some tips from Adobe and installed Suitcase Fusion 5 but it didn't make any difference.
I've run out of ideas and and don't know what to do. If I can avoid it I don't want to change back the settings to Japanese (which was pre-installed by my school without asking me) since it was really hard to navigate, not being my native language. I really need the program for class, and I'm starting to fall way behind! Is there anyone who has had the same problem and know how to fix it? Please help!

Well you have a conflict and if you tell us about plug ins free fonts you installed and other software you have installed we might be able to help but as describe the way you are going about this I have a feeling you are either doing more then you should be or are not doing everything in order, at least it seems that way to me.
What I think that would be the better way to go about this is for you to do an archival reinstall of the system, good thing to do once in a while any way.
BTW removing the fonts won't clear the font cache so if you remove the fonts you clean the font cache out then trash the Settings folder and .plist of course without Illustrator running and for safety sake restart the computer then try to launch Illustrator of course you have to uninstall Suitcase you cannot run Suitcase with Illustrator and you cannot have it installed.
Disabling it means nothing.
Those are your options.
Let me ask you something and do not get offended r you a control person?
If so let someone else handle this for you.
You will be happier.
Do you still have suitcase installed? It has to be uninstalled
Hi Wade,
Not sure what you mean by control person but it is my personal computer at home. I only ever use Suitcase to handle my font's, I never add them to the System Fonts or through Fontbook. That said, I removed Suitcase yesterday and I think I got rid of all it's various attachments like prefs, plsts or whatever. At least I hope so. I also removed Office 2004 and Illustrator has been removed with all its attachments, twice. I've also used a program called FontNuke to clear the Font cache.
I thought about reformatting the HD but wanted to see if I could find a solution before putting up the white flag. I agree, formatting is good once in a while.
