Error when running the frosty launcher

[johnny_a307]

When I run the frosty launcher to install the mods I get this error and the program automatically closes, could someone help me?

Also in the "log" tab I get this:
[10:36:44 a.m. m.]: [Core] Frosty Mod Manager v1.0.6.2
[10:37:15 a.m. m.]: [Core] (WARNING) Custom Mods Directory does not exist, using default instead

I'm going to share my experience, hope it helps people who are having trouble.
