Zbrush crash when trying to save anything

[system]

Hi,
i’m tested Zbrush 4R2, 4R3 and 4R4 but the same thing is happening. When i try to save a tool, a document or a project the program crashes.

My pc specs are 64bits quad core, 8gb ram, 1tera HD and 1gb video.

In the Memory allocation menu, zbrush only recognizes 4gb of ram. Setting it to grab 3gb and only 2 undos dont chance nothing.

Anyone has any idea how to solve this?

Thx

no clue what you have going on.

My last try was with 4R3 version. After the reboot, zbrush work like it should. Saving and everything, but after some time the problem returns.

Bizarre stuff.
