Hi everyone,

I am new to Maple, and require the use of grtensorii in my research. The package is installed correctly and will open fine, but it has troubles in finding the metric files to use. When I try to qload the metric I want I get the error message:

Error, (in qload) Could not find metric perturbed.

I have spoken to some colleagues who ran into similar issues making grtensor compatible with Maple 15, and they ran the commands

unprotect(sqrt);
