Repeated failure made me very sad.. help me

Hi, my name is Sung Woo, Choi from South Korea.
I printed some output using Form 1 and at first, From 1 printed very well.
But since I experienced first fail to print, I have failed repeatedly.

I brought the new clear resin from Formlabs, and I changed my resin tank. But It doesn’t work.
2 days ago, after printing there were nothing on build platform. So I cleaned my resin tank using IPA and used new resin, but It doesn’t work.
Then, I calibrated the build platform’s height to 0.2mm and 0.5mm. After printing, there were support base but printing was failed.

Repeated failure of 3D printing using Form 1 make me very very frustrated (I’m already sad about recent marine accident in my country, so the sadness may doubled, I think.)

Would you help me?
