loading error?

It seems that there is some error in loading Components...

I'm very sorry that the picture and attached txt is in Japanese...I hope the error name inside the braces will show some evidence

my environment is...

windows 7 64-bit

Rhino 5.0  WIP(latest ver.)

grasshopper version 0.80050

the attached is the loading exception txt that was generated by chosing 'Export'. from the dialog, the version seems to be different compared to what I'm using(0.80020 and 0.80050)
