I recieved the OSTC this week and I've been testing some basic stuff right now. So far, I like it

For some reason, I can load the settings of the computer in JDiveLog, but I can't write them to the computer. Whenever I press 'save' in the 'OSTC settings' of jdivelog, the 'transfer of data fails' (Comm-Timeout). Is this an OSTC or a jdivelog issue or how can I test what's wrong?
Another small issue is that whenever I make a simulation, it is at the present time. Is it possible to make simulations in the future? I mean, if today I want to simulate 3 or 4 dives for this weekend, is that possible (e.g. with jdivelog)?
Thanks a lot,
Kurt Sys
