why my waveform cache can upload only once, I have to re-enable HWTest driver to refresh it everytime

Hello all,
I'm using SORA to transmit a waveform file. I used DUT and UMXSample. When I want to upload another new waveform file, I have to disable the HWTest driver then re-enable it, or I have to restart my computer.
This is very inconvenient~ Do you know how to solve this problem?
Thx in advance!

My OS: Win XP, SP3
Hardware: SORA RCB + USRP XCVR 2450
When I transfered a new waveform file, the return values are always OK, but the signal shown on spectrum analyzer is not correct.
For example:
------------
E:\SoraSDK1.1\bin>dut start
Ret:0x00000000
E:\SoraSDK1.1\bin>dut centralfreq --value 2422
Ret: 0x00000000
E:\SoraSDK1.1\bin>dut freqoffset --value 10000
Ret: 0x00000000
E:\SoraSDK1.1\bin>dut txgain --value 0x1800
Ret: 0x00000000
E:\SoraSDK1.1\bin>dut transfer --file e:\waveform_pss_data0_gain40_totallen30720
0.sig
Ret:0x00000000
