Tx Loader crashes with ShaderMods

[DrParadox7]

I've recently switched from Resource Loader to TX Loader.
However this came with an incompatibility with shaders.

Tx Loader, when launched with Optifine _HD_E7 on Minecraft 1.7.10 it causes crashes with java.nio.file.InvalidPathException when shaders are selected and the player is in a world.

Without a shader loaded to Optifine, everything works fine still.

Version: txloader-1.5.3.jar

Seems like this PR in the GTNH fork brought up the same issue: GTNewHorizons#8
