Error when trying to use an object

[KAOS]

When I try to use an object (like fireplace, drying rack, stone table) for a new project, I get one of the following errors:

ERROR: You cannot use this machine as you are not on the same location.=

ERROR: This machine is already in use, possibly by someone else.=

Today it happened to me for the first time and the bug is repeatable with different characters and different objects.

I can't reproduce it. The only similar bug I'm aware of is that if you enter the start new project on a machine menu, then go back using the browser back button and try to start a project on another machine, it will say you cannot take this fixed object. Which browser are you using and did it get an update recently?

Now I tried again (was logged out in the meantime) and there's still the same problem.
I use Firefox and have no idea about recent updates (apart from "about Firefox" says it's 5.0 and it's up-to-date), because this is on my boyfriend's computer and unfortunately he doesn't play Cantr himself.

I just used a machine with one of your characters, so it's not something on Cantr's end. I'd try clearing your cache, and if that doesn't work, try a different browser.

Thanks.
It still doesn't work for me, although I cleared the cache. But tomorrow I'll be back home, so my problem is not of the biggest relevance.
