Fluid creation


I have a problem with my scene in which I want to use fluids. I have a mesh looking like a lion I want to use for the fluid. So I activated fluid simulation, setting it to fluid (with volume option), created a domain and everything is working fine. At frame 0 the correct shape of the lion is turned into fluid.
Now the strange thing: I copied the blend-file to another PC (faster) to do the fluid sim but when I start it, on frame 0 the body of fluid is not created correctly. On the left side it looks like inverted (the lion is no fluid but a rectengular shape around it, on the right side parts of the lion (not all) are turned to fluid.
I’ts exactly the same blendfile as on the original PC where the fluid is created correctly.

Is there any idea where I can look for? Thanx in advance.
