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!
