I'm using trial version of Multilizer and can't do some action. Is this limitation of evaluation version?

No. Evaluation version has only two limitations:

1. Evaluation period is limited. Evaluation period for Enterprise and Pro editions is 30 days.

2. Evaluation version puts so called 'nag' text to translation of random rows in project.

In all other aspects evaluation version functionality is identical to commercial version.

If you have any problems during evaluation period or miss some functionality - please contact support(at)multilizer.com
