URGENT – Plugin crashes pages

I had a misfortune to upgrade an hour ago to the latest version of all plugins and wordpress.
After that pages started loading 50 % of the time and quite randomly. 2 types of mistakes were showed:
1) shorter version which stated basic info about CFF and one page of java code even on pages where there is no calculators;
2) longer version which starts like this
fbuilderjQuery=(typeof fbuilderjQuery!='undefined')?fbuilderjQuery:jQuery;fbuilderjQuery(window).bind('pageshow',function(event){if(typeof event.originalEvent['persisted']!='undefined'&&event.originalEvent['persisted'])location.reload();});fbuilderjQuery(function(){(function($){$.fbuilder=$.fbuilder||{};$.fbuilder['objName']='fbuilderjQuery';;(function(root){var lib={};lib.cf_logical_version='0.1';lib.IF=function(_if,_then,_else){if(_if){return(typeof _then==='undefined')?true:_then;}else{return(typeof _else==='undefined')?false:_else;}};lib.AND=function(){for(var i=0,h=arguments.length;i<h;i++){if(!arguments[i]){return false;}}

and then goes on like that for 10 pages.

When they did load – calculators worked just fine.

Disabling other plugins didn`t help. Also changing load method and ticking “javascript cache” box. The only thing that worked was disabling your plugin. But, of course, now all the calculators are gone.

Unfortunately I couldn`t find the previous version of CFF. Is there any link to it?
And what can I do to return the calculators?
