Hi Ruslan: macAir...OSX 10.65...rb2010r5 I was using V4RB v4.7 using the following code.. Valentina.Init(10*1024*1024,strV,"") strV is an obfuscated version of my registration number/letter It fails... If I leave off the ,strV,""...it runs.... How do I initiate valentina with my registration? Thanks Harry & Chuck
