[Plugin: Shashin] WordPress multi-site support

Hello,
I’ve been testing Shashin with WordPress multi-site.
It is the first time I use the plugin and I get the following error when I try to add the feed in a sub site.

Shashin Error:

Database query failed for SQL statement: insert into wp_2_shashin_album (albumType,sourceId,dataUrl,user,name,linkUrl,title,description,location,coverPhotoUrl,photoCount, pubDate,geoPos,lastSync,includeInRandom) values …

The error continues for quite some more text.
I do not get the error when I insert the same RSS into the main site.
Is there any workaround at the moment.
I have checked your website and WordPress multi-site support is a future feature.
Thank you
