Error while loading ngram

Hi everyone,

I have met an error message like that

I don’t know where that message throws from and is there anyone can tell me how to fix it.
Thanks everyone,

What version of LT are you using? The stand-alone one or the LibreOffice add-on?

I am using the standard-alone version.

The latest one, i.e. 3.7? Could you check what’s in your libs folder inside the LT directory? How do you start LT, by clicking the languagetool.jar file I guess?

Yes, I start LT by clicking the languagetool.jar file. I think the cause of error is Lucene library. LT used Lucene 5.5.3 and the lastest version of Lucene is 6.5.0.

Yes, but we provide the proper library for that (libs/lucene-backward-codecs.jar), that’s why I asked for the contents of your libs folder. With LT 3.7, I cannot reproduce your issue, sorry.

Ok, don’t bother it. You helped so lots. You answered a lot of my questions. I’m very appreciative.
