[FIXED] The parameter is incorrect

I purchased FontCreator version 12. After updating to version 13, I found some bugs: when I clicked on OpenType Designer: Edit Kerning and OpenType Layout Features button, the message box appeared with the text “The parameter is incorrect”. Then, I clicked OK the message box disappeared and lead me to OpenType Designer. Here I can create features and classes (It also show: The parameter is incorrect when I clicked any buttons as attached pictures). After creating class all buttons (Apply, Ok, Cancel and Help) and other buttons are dead. Pictures are attached.
Please be informed that I work on Khmer Unicode font. Khmer is a single official language of Cambodia. It is spoken by nearly 90% of the country’s population.

Thank in advance for solving this bug.

Can you please send the font project to use, so we can look into the problem?

Dear Erwin Denissen,

First of all, I would like to thank for your willing to support me.
Yesterday, I uninstalled FontCreator, then re-downloaded software and re-installed it again, and now that seems to work well.
So, the problem is solved.

Best regards,

Lana

That is good to know. We did release an update yesterday, so that release seems to have solved the issue.
