Error upon 1.5.5 update

Hello,

I was testing out Cartflows on a new site, I started with version 1.5.4 last week and noticed there was an update yesterday, but upon 1.5.5 update I get this error which kills my site:

An error of type E_PARSE was caused in line 194 of the file /wp-content/plugins/cartflows/classes/class-cartflows-importer.php. Error message: syntax error, unexpected ‘)’

I rolled back to 1.5.4 for now and it’s fine again. I checked that file referenced on both versions and they’re identical, so not sure what the issue is. Thanks.
