Cycle detected in embedded blocks: Cannot open file or directory

I made a block called REG-G-UT at the directory C:\GT2\Controle\FC\REG-G-UT (R,3,0,0,3)\REG-G-UT (R,3,0,0,3).vsm. Then I opened a new diagram at C:\GT2\Controle\Doc\Teste da função REG-G-UT\REG-G-UT (R,3,0,0,3).vsm and used and an embed block to use the block created earlier. Sometimes after pressing OK after defining the File Name at the Embed Properties dialog I get the error message: "Cycle detected in embedded blocks: Cannot open file or directory ". Sometimes it works right away and I can use the block without any issues.

Find attached an image of the error occurring and the block diagram.

Leonardo, You should choose a

Leonardo, You should choose a different file name for the included embed file from the master file. That will avoid such confusion in the future.
