HP Prime programmable eq solver

[LarsF]

I think I got some problem after creating this variables, if I try to enter LIST editor or MEM, then the calculator reboots!! I'm not sure if the EQLIB, EQLIBNAME and EQTYPE is cause of these problem but there are suspicious. Is there a way to delete these variables? I tried to do a EQLIB:={}, but the variable remains as a variable and the MEM and LIST editor still reboots calculator....
