Mysql errors in working tables during migration

Hello,
just a heads up.
After migrating website which was using this plugin, I got an error while importing tables:

wp_ig_contactmeta
wp_ig_contact_meta

error was:

#1709 – Index column size too large. The maximum column size is 767 bytes.

My provider uses mysql server 5.6.

I had to cut out the tables from the SQL file in order to import all the remaining tables correctly.
Strangely, de-activating and re-activating the plugin did not produce the creation of the tables again.

My site now runs fine, but I just wanted to give this feedback, it’s possible that others run into this problem. I hope that the tables I did not transfer are recreated automatically when needed.
