N6131 - java app problem - java.io.IOException

Question

Hi,
I need to help with the following problem - I convert e-books from TXT to the phone (my mother's 6131) using free soft Readmaniac that can take a TXT file and a font file and create a Java application. Unfortunately, my mother recently has following problem (I checked it and it is sure) - she cannot even open one book and th device always says:
 java.io.IOException:
No free space to create file BOOK.IDX: .... error
although the java app file si located on a 2GB microSD card - the phone sees it without problem and there is there more than 90% free on the card. Deleting a few books does not help. For some time - about the first twenty books, it worked fine, but in recent times this is the third time it crashed. Other applications - Dictionary Kodi, Frozen Bubble (microFB), etc. are going to continue to run without a problem.
There always arise files with 'crash' in the title, suffix RMS, deleting them helps for a short time. Does anybody know, where could be problem? I used readmaniac for a long time my phone (SE K300i) and never had problems.
thanks for any tips
PS: the phone was bought in local Vodafone store (I think it has slightly customized software), but currently there is O2 sim card.

*"but i have had a couple spontaneous system shut downs where the screen has just gone black and i have had to do full restarts since the upgrade also so wondering if something got misrouted when that happened."*
*You didn't once make any reference to system glitches*. What you need to do at this point is get your install disk and check the boot disk for errors.
Restart your Mac while holding down the C key, pressing the power button and inserting your install disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities/Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. When Disk Utility is finished, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
If you do not feel confident enough to do maintenance on your iMac, then you need to take it in for repairs.
