Cant activate V4 moules since purchasing V5

Hi I am still running v4 on my live system but am building a new system and have purchased the licence for V5.
since activating V5 the modules I purchased on V4 wont activate and we keep getting the activation messages.

Please Help

Did you clear license keys and try reactivate them?

Well sharing single account on separate SambaPOS versions might create issues. You can create a new account for V5 license and let me know new account name so I can transfer V5 license to your new account.
