When you first ran this game was there an internet or Steam outage, anything like that, so it ran while offline?
Apparently if when you first run I:R you don’t have internet access, a flag is set somewhere and the game puts up a message saying MP play is not allowed, even when internet access is restored. Here’s what fixed this for other users:
- Uninstalled I:R and every folder on AppData and on Users/Documents/ relating to it.
- Did the same with every file related to Steam.
- Unbound PDX & Steam accounts.
- Deleted every entry on Windows registry related to Imperator.
- Erased the Temp folder on AppData.
- Restarted the pc.
- Linked Steam & PDX accounts.
- Downloaded Steam & I:R.
A lot to do I know! I really hope it works ... let me know!
