Question: 

I tried the new update, but when I try to open an old file, the following error message appears:

Can you help me?

Solution:

• close RAMMS
• remove this directory: “C:\Users\<your username>\.idl”    (if you specified Preferences in RAMMS, then you have to re-set them)
• now you should be able to start and use the new version. I strongly suggest only to use the new version (Rockfall) from now on. The speed of the handling is much improved, much easier to use RAMMS!
• if you again use the old version (Rockfall), then this problem could happen again…….
