What does this message from JJ mean

I updated to JJ OS 2 last night. JJ sent me an e-mail today with the following content...


"The next version (Ver0.80) of OS2 can be updated only from Ver4.98 or more version of OS1.It does not start, even if it updates by Ver4.97.Moreover, it cannot update from screen of load of Ver0.72.Ver0.80 or more updates can be performed from the load screen of Ver0.80"

What the heck does he mean?

it means that you can't load version .80 of OS2 unless you have version 4.98 of OS1, so install version 4.98 of OS1 and then you can load version .80 of OS2.

cheers. All these versions/updates are confusing me!
