i have LJP and i used UDMH for LJP to work.

Now UDMH expired and LJP doesn't work.

i don't want to buy UDMH and i was wondering if there is a similar app that will
make my LJP work for free.

There most be some app that is the same that is freeware/shareware?

Please help me out.
I want to play LJP, it is the thing i most use at work.
THanks to all.
