is any way to check it?

when i want to install sth then this is displaying: Trying to open URL: package_*.xml. nothing is happening then. file exists but i don't know what should i do. i chmoded templates and plugins dir. it didn't help.

thanks a lot for that

i saw that package_*_pl.xml doesn't exists. for any other language it is, but not for polish. is any way to fix it? could you make that file?
