Hello,
I tried to export schematic file from EasyEDA version 6.4.19.4 to Altium version 21.3.1 (Build 25) and got the error "<span class="colour" style="color: rgb(85, 85, 85);">Load file error: Value was either too large or too small for an unsigned byte".</span>
<span class="colour" style="color: rgb(85, 85, 85);">Layout file exported fine. </span>
<span class="colour" style="color: rgb(85, 85, 85);">What is the problem.</span>
<span class="colour" style="color: rgb(85, 85, 85);">Thanks</span>
