Dropping visitors

[harleyforum.se]

Story:

1. I had the free version, 2.2.4 for a month or so. Worked great, got many many more visitors to the site!
Running (i.e. 'address?language=en') links on this version.

Now (problem):

2. Bought and installed the license version 4.4.2. Changed the settings in the forum according to your readme file.
A. Changed from (i.e. 'address?language=en') to (i.e. '/en/address')
B. placed your .htaccess file in the root as is. No changes to the file at all.
C. Changed conical webaddresses to STRICT and also change to Advanced type of url:s

Suddenly visits dropped to amost half within a week. Got error messages like, "TO_MANY_REDIRECTS" when creating posts on my forum and clinking on links to my forum from facebook etc. Also Google admin tools reported many broken links etc, all of them linked to languagelinks. an, fr sv etc.

Number 2A is still the the same setting (/en/) and htaccess file still there.

Today Changed back advanced to standard URL, and also removed STRICT to std. and l´now links starting to work again....anything you know of before?

I have now disabled translate software for the time beeing.

Any suggestions what to do?! I do want the translatesystem active. Thats why I bought it
