Troubleshooting GRTensorII Error in Maple 12: Unable to Load Metric

[Polyrhythmic]

Hey!

I'm running GRTensorII version 1.79 on Maple 12. When I try to load a metric, I get the following message
Error, (in grload) unable to read `C:/Programme(x86)/Maple12/metrics/kerr.mpl`

I've installed everything according to the guide, but it just won't work.

Maybe anybody has an idea what the reason might be?

Thanks in advance!

It's several years since I've used GRTensor but I do recall that the mapleinit file is quite sensitive to the proper identification of the path to your GRTensor directories. In particular, I seem to remember that it was picky over the correct use of quotes to delimit the path, as well as some issues relating to the use of backslashes over forward slashes in the path.

It's fiddly, but keep playing around with it and you'll get there.
