Power amour/tinker table not working

[bignose956]

I was playing on Voltz version 2.0.4 on nice little server, I had just made some power armor and a power fist. When I selected my power fist on my hot bar, my hot bar started flashing endlessly. I ignored it and went on to making my power armor tinker table, but when I opened the tinker table, the whole screen started flashing (Like this) and I could not play Voltz.

If you’re going to tell me to play a newer version of Voltz, forget it. I can’t run any other version. I can only run the recommended version.

Please help me find a solution!

Thank you!
